Well the Alpha demo wouldn't run on anything less than a pretty hefty shader-capable card, so that seems pretty certain. In fact, I think Mark specifically said he was unsure of whether or not he would support non-shader cards.
A lot of programmers seem to have found problems when mixing fixed-function with shaders and stick to one or the other.

I can't pretend I'm happy about the ( very premature, in my opinion ) switch of focus to the 3d module though. I understand why a lot of people want it, obviously. But those of us who've already bought it and are trying to make something with it are suffering pretty badly in the meantime with missing features, poor docs and quite a collection of bugs.
