Forum:Why is ME1 not on the PS3?

ME2 and ME3 are on the PS3 but ME1 isnt why is that? i just started getting interested in ME but i have a PS3 not an XBOX which means if i want to play ME im gonna miss the what happens in the first game which is a giant chunk of the story :( . Is there any chance for ME1 to come to the PS3?
