User blog:Traditionalfire/Save file transfer

Im planning to get ME2 and ME3 to PC and i wonder about save file transfering. I got the first ME from Steam and i wonder, can you get ME2 from Origin? And can you transfer a save from the Steam version of ME to the Origin version of ME2? (if it exsists) If ME2 don't exsist on Origin then i wonder the same thing for save file transfering from the steam version of ME2 to the Origin version of ME3.
