I believe how this is handled from past experiences, is that you enter the pre-order key either from an Online order (Emailed key) or from and instore preorder retail box (Key with CD). You must install the game from a download, info from the preorder email, or from the CD. This will then allow you to get into the game "up to 3 days early" and play on the LIVE servers.

You will then get your retail key upon release of the game which is then added to your acct info. In past games there has been a layover time from the offical launch and the time you needed to enter the retail key to allow for shipping. Hope this helps alittle on the questions you had.
