It's also worth note to mention that you will not get any of your digital items until you enter your product code. So even though I redeemed my pre-order code, and it says I have the collectors edition pre-ordered, I don't have any of my items, and wont get them until I enter my product code that comes in the game box (or is emailed to you by Origin when the game launches).
This is to prevent things such as someone registering a collectors edition pre-order code but actually only buying a standard edition from getting the items he/she is not entitled to. Even for only a few days.
