Yay I get to go first and I love speculating on hardware.
My best guess is something like this:
RAM:
1024 MB of GDDR 5 this will probably yield around 50-80GB/S bandwidth. The best balance between cost/performance is around that level and it follows the current RAM size / bandwidth ratios of current generation systems and the expected trends for next generation systems. Doubling this would require 8 chips which would be cost prohibitive and won't yield good performance/price ratios as the bandwidth wouldn't scale with any increase in capacity.
Optical Drive:
4-8* Blu Ray, what else can I say?
CPU:
X86/PPC equivalent to a fast Core 2 Duo.
GPU:
~between an HD 4850 or HD 5770 in outright performance, feature set could be DX10 or DX11.
Storage:
Something like 8GB of Flash.
lol, my explanations died out. Anyway the RAM thing probably needed the most explanation and the rest sort of feels like 6 of this compared to half a dozen of the same. Different terminology yielding the same result.
Tease.
