I have seen a number of posts asking about access codes..........well if you pre-ordered from Newegg you are SOL. Newegg is not a preferred retailer and thus has no access codes to sent you regardless of what their site and links say. At best you will still get the explorers pack but no early access (which IS the reason whey we are all pre-ordering and not some silly pet)
If you still want 3 day access your best bet would be to cancel your pre-order with Newegg asap and go to Amazon who are authorized. They state you will get the code within 2 days of pre-ordering so don't wait too long!
I just barely dodged this little bullet and thank the gods I didn't wait until Monday night to find this out.
