I havn’t read though them all yet, but the more paranoid will be reassured by the OpenGL/Vista notes (although it doesn’t really add anything new). Personally I think the new object model and the 3.0 “lean and mean” stuff looks very promising, although it’ll be a while before it’s actually widespread enough to use.
Geometry shaders sound very nice too, would remove quite a few of the nastier hacks used with existing shaders I think.
Edit: conditional rendering too. About time really, as thats been available on other platforms for a while now. ;D
