they have yet to untap the full potential of the PS3 yet, hell they are just now maxing out what the PS2 can do, look at the games that originally came out on PS2, and now look at what comes out for it, the same thing will happen with PS3, they look great now, but in 2-3 years they will actually be able to use the full potential and we will be blown away... it takes time to learn the best coding methods for games on different consoles...
for example, look at the game BLACK for PS2.... hollllllly sh!T, those graphics compete with what currently comes out on 360 and probably half of the PS3 library...
point being, the consoles still have room to grow and until then there is no point in another console because we havn't even seen what the current ones can do yet
