i think we'll move in the doom 3 direction, by having more and more rendering passes, and longer shader programs. However, im pretty sure we'll see some good use of displacement mapping (like bump mapping only you make actualy changes to the polygons, it doesn't just look like it), but it isn't implemented all that well in dx9, so that'll probably wait until the next release.

but yeah, AI will be afforded more CPU cycles, so it'll be fun to see what kind of a difference it makes
