Best Buy has a similar sale going on this week as the Toys R Us and Amazon sales last week. I'm definitely eying Uncharted 2 and Ratchet and Clank. Doesn't include pre-orders but you could always just buy a game and exchange it when another that you want comes out. I'm gonna do that for Assassin's Creed 2.
