To answer the poor guys question, I'd say any Sears that carry video games should. But I'd be sure to call and ask ahead of time to be sure..
Kohl's only carries games (and generally older games that sell on ebay for about $5 max, and they try to sell for $20), and I haven't been in a Pennys in ages, so I don't know about them.
Let's try to work on a list of stores that should have on launch date.

Best Buy
Circuit City
WalMart
Sam's Club
