It'll be watered down bullshit. And I don't get how anyone can like those graphics. If they can't do 3D well (see: Rome Total War) then don't do it at all. I'm not saying the graphics in the previous 3 Civ games were spectactular, but they were perfect for what the game intends to be. I don't know what the hell 4 is supposed to be.
Also, all this talk about "streamlining" features is awfully familiar. I'm betting on a 90% chance Civ 4 will be a catastrophe.
