While I agree with you that Forza 7 will be 4k/60fps, but I don't think we will see dynamic weather, dynamic lighting etc. if they are aiming for 4k/60fps. That is a lot to ask for out of a 6tf machine. The one main thing Forza has been missing, well outside of some good AA is dynamic lighting/weather. I would most likely prefer 1080p/60fps, high level AA to eliminate jaggies, dynamic lighting/weather, AFx16, improve shadows, detailed 3d crowds and scenery and a field of 32 cars both on-line and off-line. With a 6tf system this could easily be done.
