For the fun of it, I just had to find the sources of this remarkable list.
Here's what I found in this short time:
1879 - Will be resurrected
The Watchtower 1979, p. 7,8:
Surely if we find their restitution mentioned you will be satisfied: But why should they not have an opportunity to obtain eternal life as well as you or the Jew? They were not wicked in the proper sense, for they did not have law or much knowledge. True, they were not righteous, but neither were you when God gave you your opportunity. Christ’s own words shall tell us that they are mot as guilt?/ in His sight as the Jews, who had more knowledge: “Woe unto thee, Capernaum, for if the mighty works which have been done in thee had been done in Sodom it would have remained unto this day.” Thus Christ’s own words teach us that thev had not had their full opportunity. “Remember,” Christ says of the Sodomites, that “God-rained down fire and destroyed them all.” So, if theii restoration is spoken of, it implies their resurrection.
1955 - Will not be resurrected
The Watchtower 15. November 1955, p. 676:
That some will not gain salvation is made clear in the Bible from Genesis through Revelation. In sentencing Adam God said: “For dust you are and to dust you will return.” That means annihilation, not salvation. Regarding Sodom and Gomorrah we are told that they “are placed before us as a warning example by undergoing” judicial everlasting punishment. At Revelation 21:8 (NW) we read that all the wicked will have their portion “in the lake that burns with fire and sulphur. This means the second death.” Nothing is said about a redemption or a resurrection from this second death.—Gen. 3:19; Jude 7, NW.
1965 - Will be resurrected
The Watchtower 1. March 1965, p. 138:
17 So the inhabitants of Sodom and Gomorrah were made a “warning example,” because they were not allowed to continue existing till the day of Jesus Christ and of Peter and Jude and fellow disciples. Not that the people of Sodom and Gomorrah were condemned to Gehenna and were hurled into the “lake that burns with fire and sulphur”; but that they were made a warning example to unfaithful Christians (”ungodly persons”) who will be judicially punished with “everlasting fire” or everlasting destruction.
1967 - Will not be resurrected
The Watchtower 1. July 1967, p. 409:
How will these, having been caught, be disposed of? Will they be preserved alive? Will they be killed and buried in Hades or Sheol, which is the common grave of dead mankind, from which resurrection is possible? No, these political organizations are slated to be “hurled into the fiery lake that burns with sulphur.” This the Bible describes as the “second death.” (Rev. 20:14) It means the death from which there is no resurrection. They will be burned up root and branch, as completely gone forever as the cities of Sodom and Gomorrah, which Jehovah God burned up by a rain of fire and sulphur from heaven, never to be rebuilt. It is destruction in Gehenna in which God destroys both body and soul (any right or possibility of living).—Matt. 10:28; Gen. 19:23-29; 2 Pet. 2:6-9; Jude 7.
1974 - Will be resurrected
The Watchtower 8. October 1974, p. 20:
God’s dealing with Sodom and Gomorrah shows that he takes no pleasure in the death of anyone, but wants all to live, if they will just live respectfully toward their fellowman and in obedience to righteous principles. (Ezek. 33:11; Mic. 6:8) Moreover, God’s undeserved kindness and care are so great that he will bring back the people of Sodom by a resurrection, with opportunity to learn and turn around to the way of life, even as his Son stated.—Luke 10:11, 12; Matt. 11:24.
The Watchtower 15. August 1982, p. 26:
10 Sodom, Gomorrah and surrounding cities furnished a warning example “by undergoing [Jehovah God’s] judicial punishment of everlasting fire,” eternal destruction. The charred ruins of at least Sodom, Gomorrah, Admah and Zeboiim are thought to lie under the waters of the southern portion of the Salt (Dead) Sea or in that region. So neither they nor their inhabitants are still burning. Apparently the cities themselves, rather than all their inhabitants, were everlastingly destroyed, for it seems that at least some individuals once residing there will be resurrected. (Matthew 10:15; 11:24; Revelation 20:12, 13)
1988 - Will not be resurrected
The Watchtower 1. June 1988, p. 30:
There is an interesting similarity in phraseology between this description and what Jude said occurred in the case of Sodom. Furthermore, Matthew 25:31-46 and Revelation 19:11-21 indicate that “the goats” cut off in the coming war of God will experience “everlasting cutting-off” in “the lake of fire,” which symbolizes permanent annihilation.—Revelation 20:10, 14. Consequently, in addition to what Jude 7 says, the Bible uses Sodom/Gomorrah and the Flood as patterns for the destructive end of the present wicked system. It is apparent, then, that those whom God executed in those past judgments experienced irreversible destruction.
1988 - Will be resurrected
Insight, Vol. 1 p. 985 (Gomorrah):
The apostle Peter said that by reducing Sodom and Gomorrah to ashes, God condemned them, “setting a pattern for ungodly persons of things to come.” (2Pe 2:6) This mention by Peter and references by Jesus Christ and Jude prove that Jesus and his disciples acknowledged that these cities of the District had actually existed and that they accepted the Biblical account of them as true. Though the cities underwent “the judicial punishment of everlasting fire” (Jude 7), Jesus indicated that people of Sodom and Gomorrah would experience a resurrection to stand for judgment. He contrasted them with a city that rejected his disciples in their preaching of the Kingdom good news, saying: “It will be more endurable for the land of Sodom and Gomorrah on Judgment Day than for that city.”—Mt 10:7, 14, 15;
1989 - Will not be resurrected
Live forever... (1989) Chap. 21, p. 179:
Will such terribly wicked persons be resurrected during Judgment Day? The Scriptures indicate that apparently they will not. For example, one of Jesus’ inspired disciples, Jude, wrote first about the angels that forsook their place in heaven to have relations with the daughters of men. Then he added: “So too Sodom and Gomorrah and the cities about them, after they in the same manner as the foregoing ones had committed fornication excessively and gone out after flesh for unnatural use, are placed before us as a warning example by undergoing the judicial punishment of everlasting fire.” (Jude 6, 7; Genesis 6:1, 2) Yes, for their excessive immorality the people of Sodom and of the surrounding cities suffered a destruction from which they will apparently never be resurrected.—2 Peter 2:4-6, 9, 10a.
This is of course no big deal compared to the blood question, but I find it interesting that they would bother to flip-flop this much over a no-big-deal-case.
That makes it even more interesting for me
