I sold my old computer for $800 a week ago, I'm going to take $600 and buy the new PS3.

I read online that each store is only going to have 10 - 15 PS3s? If this is true, I'm never going to get one, considering there's already a line outside my local Target and Best Buy of people camping out to be the first people to get it. When do we get the next shipment?
