No, FFXIII will not be downgraded like GTAIV.

It's not more memory capable. On the contrary. It just has shared memory which makes it more memory flexible. Ps3 has an equal amount of ram and half of them perform at twice the speed. So that would be the more capable one.

 

256MB or 512MB for graphics. The choice is easy which one is more capable.

 

its actually

256 mb XDR 3.2ghz main memory + 256MB DDR3 700mhz memory VS 512mb DDR3 on the 360,

it not when to use one they other can't be used. actually u can use both fully. actually kz2 developers walkthrough we say killzone development memory usage and were split around 400mb between the 2.
