It would not make sense to make ME2 for the PS3, the first game ties in with the trilogy and PS3 owners would be playing a game without any clue on what the story was about. Also from what I remember the sequels would carry on from the first i.e. whatever your actions in the first game carry over to the next.

That hasn't stopped 'em bringing far cry 2 to PS3, from what I hear Mass Effect wasn't as great as it claimed to be

Yes but FarCry 2 does not lead on from the previous game.

ME was not great it was ok, a lot of the things that were really cool and awesome that the devs showed in vids etc was all taken out and left with a mediocre version. Also there was a lot of stuttering in the frame rate.

oh right, didn't know FC2 didn't follow on.

I don't know, I'd like to have Mass Effect 2 on the PS3, considering the Xbox in my house isn't mine. Remember, Shenmue II was released on the Xbox and to make up for lost storyline, they bunged a DVD with a movie featuring all the events of Shenmue I. It wouldn't be absurd to consider a Blu-Ray with major plot scenes/recap of Mass Effect 1 in a PS2 ME2 package.
