Uncharted 2 comes out next month, but already the game is skyrocketing to the top of sales charts. According to Amazon the game has been in the top 3 of sales all week for video games. In the PlayStation section it has been number one, with Uncharted Drakes Fortune at number 2.

It’s a good thing to note that Amazon sales are not official numbers; they are updated daily based on how many people buy the game. However if you want an example of how well its selling, the recently released Halo ODST is in first place, with the absolutely free Cake Mania in second place, maybe you should go download it on your work computer? PS3 120GB Is still in the top ten as well, being the only console still in the top ten ranked at 8.

Amazon is also offering a free “Treasure Map” with all pre-orders, while Gamestop is currently offering the demo to early pre-orders. However demo codes at Gamestops seem to be in a low supply as of now, so that could be another clear sign of strong sales in an early stage.
