Early Access is based on the code you have already redeemed. As of the 16th Origin will start to send out the actual game codes to those who purchased, and also take the rest of the money (only a deposit has been paid to Origin)
You want to get this code onto your account ASAP, so you can continue to play - if you don't do it by the 20th you can't sign in until you redeem it, you don't lose a lot of time if you forget, but obviously it's best to do it once you get it and not leave it until the last minute
This makes a lot of sense...i'll sleep easier lol. My pre-order key will act as a "filler" until I receieve my retail CD-key for the game. Hopefully this is correct but it sounds right =] Thanks again hope this helps people.
