This was taken from the jw website when they first published the new FDS light.
It explains why there could not have been a resurrection since 1914, but is future:
When Does Jesus Appoint the Slave “Over All His Belongings”?Jesus said that the “master on arriving” (literally, “having come”) will appoint the slave “over all his belongings.” When does the Master, Jesus, arrive?
The expression translated “on arriving” is a form of the Greek word er′kho·mai. Verses 42 and 44 of chapter 24 translate a form of er′kho·mai as “coming.” In those verses, Jesus is referring to his coming as Judge during the great tribulation.—Matthew 24:30; 25:31, 32.
Jesus’ appointment of the “slave” over his “belongings,” then, must also be a future event. He will make that appointment during the great tribulation.
What Are Jesus’ “Belongings”?Jesus said: “All authority has been given me in heaven and on the earth.” (Matthew 28:18) Jesus’ “belongings” thus include more than just his earthly interests. They include the Messianic Kingdom.—Philippians 2:9-11.
Consequently, Jesus will reward “the faithful and discreet slave” by resurrecting the individual members of that group to heavenly life and by giving them royal authority over all Christ’s belongings in heaven and on earth. This is the same reward promised to all faithful anointed Christians.—Luke 22:28-30; Revelation 20:6.

So this reward is still future ("will reward").
We used to be taught that some were already resurrected and communicating truths down to earth. Well that could only be done by the FDS, and the FDS don't get their reward until the Gt Trib. Future.
Also, they have not been appointed over all the masters possessions yet - that is future too, pending that they are deemed righteous and not wicked.
So if they have not even been judged righteous or wicked yet, how can they be rewarded with resurrection to heaven?
