The graphics on the PS3 and 360 are very similar, there is very little difference between the two. Also you can get Netflix on the PS3 (you can get it on the Wii, lol), but you still have to pay the monthly fee the same way you would pay for it on the 360 .
Eh? Does that mean 360 support 3D to? (o_o)
And I guess the other different is there is a few game that are not multiplatform like Yakuza Series (For PS3 only) and Magna Charta 2 (For 360 only)
