I am hoping since speculations say that the Xbox 720 will be 10 times as powerful than the 360 it should include the following.
Triple-Screen adapter, Bluray drive, SSD instead of HDD, 3D gaming, Kinect 2.0, more sound decoder and Windows 8-like interface.
Who would like to play Call of Duty Black Ops 2 in full 1080p, 3D gaming and Dolby Digital TrueHD (7.1) on 3 Surround (180 degrees) 55" Crystal Clear HDTVs to give you a real simulation of Shooting, Driving, and other games.
I know I would. ;)
