I think it will be very powerful, with a solid state drive, and Kinect 2.0 (which will be a big upgrade.) And agree with most everyone Else's comments, cloud, social, lots of RAM, etc.
I hope it uses the, yet-to-be-seen, beauty of DirectX 12. DirectX 11 looks amazing, yet, I wouldn't want to be stuck too far behind with older tech as the PC's advance.
I'm also wondering if 4K TV are going to on the market at that time, and if the new Xbox will support the next leap to super high resolution (which will require a MUCH more powerful CUP/GPU's).
Also wondering about multiple monitor support - their driving demo at E3 with 3 monitors looked really sweet - image the feeling of Halo 4 with 3 monitors.
I think much will have to do with how Kinect sells in the next few years and how far they want to push the industry.
