well most likely gonna use heavy duty compression on everything. and max out the every on the ps3 that has a cache. more pop up with the graphics that they'll try to hide when fading in and out
ps3 has 512mb of ram, 7 core processor that atleast 5 years old by the time the game comes out. people who put a SSD in there ps3 will will get the best preformance since that will help the processor from having to bottle neck while searching the drive
