So that's why they demoed game on PS4.
And dont forget this :
"This is anecdotal from E3, but...
I've heard the architecture with the ESRAM is actually a major hurdle in development because you need to manually fill and flush it.
So unless MS's APIs have improved to the point that this is essentially automatic, the bandwidth and hardware speed are probably irrelevant.
For reference, the story going around E3 went something like this:
"ATVI was doing the CoD: Ghosts port to nextgen. It took three weeks for PS4 and came out at 90 FPS unoptimized, and four months on Xbone and came out at 15 FPS.""
