As much as I love dominions and wish that it gets as much attention as possible from IW, I think that those decisions are for IW to make.
I regard game creation as a form of art and as such no artist wants to forever repeat making the same master piece, so I can sure understand if IW wants to create a space game or something else. I will probably not like such a game (not my thing) but others might.
First things first, let see how dom-III turns out, how many patches add-ons and mods it gets, then start wishing/begging for the fourth installment
