Hopefully they will up it to 15-20, I saw in the last EGM they were expecting around 10 at launch. I preordered mine months ago, even then I'm gonna be on the second or 3rd shipment but they say it'll only be a week or 2 between shipments judging my MS's estimates.

I'm really looking forward to Full Auto, Gears of War, and rebuying Madden at launch.
