Religion might be interesting if:
But none of this matter. Religious victory isn't great, but it really isn't that much of a game killer. The game has actually completely broken stuff in it which are, once again: AI, UI and diplomacy/trade.
Do we know for certain, based on this announcement, that the devs are focussing on religion rather than those issues? No, we do not. Will the named changes be the only thing changed in the patch? Highly unlikely.
But, considering that was the focus of the only piece of information we have from them about the patch; it is entirely asinine to think that this patch will focus on the parts of the game that are actually broken rather than just inconvenient. Thinking otherwise is just a textbook example of cognitive dissonance - interpreting the available evidence to fit your desired opinion/desires rather than taking the interpretation which is vastly more probable.
