i think they did a great job for porting it, and whatever, there CANT be any big differences, since the same models were used, so those screens dont tell anything. (by watching at them, the only difference is shadowing/contrast, and who cares if both look amazin'.?)
I think ME3 will be slightly better looking at 360, judging by the few framedrops on PS3, but then again ~ i dont CARE, because i think both versions will kick ass.
@topic ~ nice comparsion though, enjoyed the read :D
