To be fair, giving out this kind of information in detail would be stupid. That would be like a movie trailer showing the ending scenes of the movie. He just shouldn't give out that many infos on the most desired events in the game, and everyone should know that. Would totally ruin any excitement of what could possibly come in the future, even though most of the stuff is obvious.
That said, we'll most likely never reach a point where stuff like that is going down, unless he's actually still developing this project in 20+ years, in which case probably 99% of the people currently following this game are either dead or have given up on it altogether.
