Ahh that makes sense.
So if they had roughly 20mb of EDRAM they wouldn't be in this mess?
What is the PS3 equivelant of the EDRAM, what allows the PS3 to have 720p images with all the nice little extras?

Yep if MS had that much Edram all 360 games would most likely be 720p with all the bells and whistles and it would probably win all multiplatform H2H without fail.
As for PS3 Edram equivalent? Doesn't have any. It has a split memory so 256MB for VRAM and extremely fast 256MB main RAM. It does have the Cell processor so programmers can off load tasks onto it's powerful SPU's and for gaming purposes it can use up to 5 of those which is what Sony first party studios do and an increasing number of third party studios are doing. So for example MLAA can be handles by one SPU, A.I by another, physics by another etc. And because it's a more traditional set up in the memory side, it doesn't have to worry about tiling. The framebuffer can be big (I think Killzone 2-3 are around 20-30MB) because the developers can use the Blu Ray space and default HDD to cache data and of course off load GPU tasks onto the Cell's SPU so the limited RAM space is alleviated.
