AFAIK it hasn't changed. When I was young, the resurrected didn't marry, so the best outcome was to stay alive til '75 so that you had a chance of a normal sex/married life, children, etc.. Second best was that your partner died, but you survived and could marry in the New World and make perfect babies. Third best, was that you died and were resurrected and were not able to marry anyone, including your ex partner, or even fiddle with their naughty bits, without being condemned to everlasting death.
I'm sure most older JWs have had this old doctrine drummed into them, the same as they tried to drum it into me, and now they have to find a way to deal with it in their last days.
