You know, Covenant, you have managed to express ALL of my key concerns-so far-about this game. The lack of mention of diplomacy-and trade-seems like a 'tacit' admission that they have done precious little to improve these still very lacking components of the game (strange given the excellent template they have in SMAC).
In addition, it feels like with victory conditions they have just gone 'what victory conditions should we add? Oh, what the hell, lets just get all the ones from Civ3 and tack them on to the end of the game!'

This is especially frustrating given their claim that this version was being built 'from the ground up'-a PERFECT opportunity to introduce lots of new and exciting victories which totally 'broke the mould' of previous civ games. Also, the fact the victories are the same also suggests that the way you achieve them will be the same too-i.e. the amount of land you have, rather than the quality of the land and/or how you use it.
As for religion, I definitely feel it lacks 'bang for the buck'. It seems like little more than a label which has an effect on happiness and diplomacy-all things which could have been done within the existing culture system. Not to blow my own trumpet, but I put forward a VERY simple, yet effective-IMHO-model for religion which was generic, but could have a MAJOR impact on overall victory and the way in which you played the game-whilst also leaving players with the maximum of choices!
I have to say that-on what I know right now-I am more likely to not buy this game than to buy it-which will be the first for me in the ENTIRE franchise

! I just hope that a lot of the info here is either wrong-or in its infancy-and that closer to the date I will start to hear stuff about the game which can REALLY grab my interest and attention!!
Yours,
