I had a preorder for the xbox 360 @ eb games but they told me that i am unable to get mine until 2-3 weeks after the initial launch date.

Im gonna just cancel my preorder and go to the store and pick it up. I know best buy is going to have it but my questions is can i buy the $399.99 one and not have to worry about buying the games and all that...also are they going to be opening early for them as well. I also no circuit shitty is going to have them for sale on friday online...

Any help
