I did know anointed jws from the 50's, 60's, 70's. The new crop seems to dwell on their "special" powers in heaven....which means they are assuming that they have received the final sealing and are not able to lose that status. The final sealing has not happened yet so any anointed jw who makes statements like that are being very, very presumptuous.

Learn From the Illustration of the Talents
12 When the master came back from his journey, he saw that the slave with five talents had earned five more and the slave with two talents had earned two more. The master told each of them: “Well done, good and faithful slave! You were faithful over a few things. I will appoint you over many things.” (Matthew 25:21, 23) What will the Master, Jesus, do when he comes in the future?
13 Just before the great tribulation, God will give his final approval to the hardworking anointed ones who are still on earth at that time. This is their final sealing. (Revelation 7:1-3) Then, before Armageddon, Jesus will reward them by raising them to heaven. But what about those with the hope of living on earth who supported the anointed in the preaching work? They will have been judged as sheep. And they will be rewarded with life on earth under the rule of God’s Kingdom.—Matthew 25:34.

“We Want to Go With You”
Do those of the other sheep need to know the names of all those who are anointed today? The short answer is no. Why not? Because even if someone has received the heavenly calling, that person has received only an invitation, not a final confirmation of the reward. That is why Satan raises up “false prophets . . . to mislead, if possible, even the chosen ones.” (Matt. 24:24) No one can know whether an anointed Christian will receive his heavenly reward until Jehovah judges that person to be worthy of such a prize. Jehovah makes this determination and gives him the final sealing either sometime before he dies faithfully or sometime before the outbreak of “the great tribulation.” (Rev. 2:10; 7:3, 14)
