Sounds like more confirmation what we already expect.
It's likely most of the "custom" part of the Xbox GPU just revolves around grafting EDRAM in. I'd still guess that relates to it's DDR/EDRAM setup vs PS4's likely GDDR/no EDRAM setup.
A lot of people seem to want to jump the gun and move PS4 over to DDR so it can have a gaudy bigger total RAM number like Durango, but I smell wishful thinking rather than true well based rumors as it stands. My guess is PS4 is still planned at 2-4GB's of GDDR.
