Why aren't Sony exclusives/software selling anywhere close to Xbox360?

[MARCUSDJACKSON]

i'm already in the middle of more then 10 games across 3 consoles(PS360,ps2) does it looklike i have time to go out a preorder a game?

also look at sells of games that have been out for 4 yrs and you'll see that most of the sell are near even for multi-platform games.
