i dont know weather or not anyone knows the answer or not, but since Ps3 users did not get to play mass effect 1. Will they have to play using a default renegade Sheppard? 
 
it seems kind of unfair to them.  
 
Ps. i have to get the Ps3 version cause my dang 360 broke down before i could get the ending i wanted, and i want the data that carries over to the 3rd one to be perfect, and i swear if wrex is dead in my world i will be pissed

There's an interactive comic in the PS3 version that goes through the story of the first game.

the comic will give you 6 choices that make up your shepard. So Which one is left behind to die Kaiden or Ashley, Does Wrex live, did you release the Rachni Queen (I don't know this one for sure :D) etc
 
All in all it will save you playing ME1 again if you want a quick ME1, ME2 playthrough at the end of the year when ME3 comes out. There is one main mission left out but I forget which as its been ages since I played ME1.
