I don't think we'll see any great games with full 1080p on the Xbox 360, ever. If you're familiar with game resolutions on the PC, you'll know a higher res means more processing power needed on the GPU, and i think the same thing applies to the Xbox 360. See even Bungie reduced Halo 3 to 640p to increase performance(usually when ppl say performance they mean framerates). Why does games like Virtua Tennis support 1080p, thats because its just a small scene with very little things to render.
