It's true because I got my reservation in (mentioned in the pre-order thread).
But it's only a backup plan. I've never had good luck getting pre-orders in a timely fashion from them.
When I pre-order stuff there, there's always an extra day or two before they finally "prepare it for shipping" and mail it. Even with overnight shipping it's possible we wouldn't get it until the following Wednesday or whatever, unless they guarantee an on-time delivery like they did the Harry Potter books or something (which isn't likely).
EBGames.com will do bundles, and they've shipped boxes early. They're a better bet if you really wanna get it asap.
