Ok I called like 5 different stores (target, Best BUy, Hastings, Ect) and they all said that they didn't have Big Brother 4 and it comes out June 29th. What's up with that?
I saw that one of the stores you named had broken street date on it last week. I'll have to let you guess which one, since we can't name names here.
The official street date is still today, according to the distributor's website, and Amazon says it's available to ship within 24 hours (i.e. "in stock").
Basically, the other stores are slow-boating it to keep shipping costs down on a title they only think will be a mild seller.
