I'm sure this is somewhere.... I have been playing the beta and the early start; I pre-ordered the game, but won't be able to get the game till Wednesday night, does that mean I won't be able to play till Wednesday?
No. You will have a grace period of "several days" before they cut off your access. The only thing you won't have access to is your retailer "bonus" items. You won't get hose unlocked till you enter your retail key.
