Mass Effect is coming out on PS in 28th January so yup what we should expect is a comparison between it and it's sis-in-law the X360:
Mass Effect 2 is Looking Good on the PS3 But this engine is going to be used on ME3 i think.
But really Bioware are respectable developers who didnt just port the game but built it for the PS3 from the ground up.
Btw guys and gals i was able to modify a setting on AC:II and AC:B so that the X360 and PS3 versions look the same and it is quiet simple just decrease the Brightness setting in each game by one point, then increase the brightness of your TV by 1 or 2 points. (in my case EX500) But be-careful my original brightness setting was on like 51 or 52.
