Japanese convenience stores have sold video games, dvds, music and concert/amusement park tickets for 10 years or more now.

The main thing holding back such glorious implementation in American stores is likely the security factor, what with our crime rate being an order of magnitude worse. Maybe this will take off and midnight release parties will become much much easier to get to. Or maybe a 7-11 clerk will get murdered and his shipment of Madden 2010 will get stolen and the practice will stop. Time will tell.
