Based on pre-order chart, it didn't have a lot buzz. I would guess less than 100K WW.
However, I'm sure no games on PSP and PS3 would underperform now since there is always PSN sales that we don't know about.
MikeB predicts that the PS3 will sell about 140 million units by the end of 2016 and triple the amount of 360s in the long run.
