Specs:
CPU: Some sort of upgraded/multi-core CELL processor or an i7 quad-core processor. Either @ around 3.4GHz.
GPU: Based on the GTX 580.
RAM: 2GB vRAM, 2-4GB Main RAM.
I put very similar specs into games-debate.com to see if it could run Battlefield 3. This build can run it at high settings at 1080p, keep in mind this is without optimization/clever coding.
I think this could launch for $400, possibly less but I doubt it because of SONYs financial situation at the moment.
Controller(s):
Dualshock 4 - keep the base design of the Dualshock 3, replace R2/L2 with triggers, make it 5-10% larger. Maybe add a rear touchpad somehow, depending on what devs to with it on VITA. Ditch sixaxis to keep costs down. Maybe put keypad on the bottom on the controller (between the handles).
Motion controls: MOVE 2, Upgraded EYETOY (which would be an upgraded Kinect).
UI:
Refined XMB, take away the clutter, make it more attractive. Put focus the network section (3 icons on the far right), redesigned PSN (includes friends list, trophies, Store etc.)
