Pick up a PlayStation Vita in the U.S. from Amazon, in the next week and you get Gravity Daze bundled for free. Quite a neat deal with the Wi-Fi model retailing for $249 and the game going for just shy of $40. Sure, its not the same thing as a price-cut, but it could help shift a few units, especially with the gaming calendar moving out of the quiet season.
The Madden 13 bundle is the same price and out at the end of August, if that's more your thing, with the white model in the Assassin's Creed III bundles coming October, just remember to add a memory card to your order.
North of the US Border, Wal-Mart in Canada also has a top offer with Wipeout 2048 and Resistance: BS free with Vita purchase.
