Bah, the problem is that by preordering the game new, I wouldn't be able to play MY account - and I don't actually want to spend SO much money. There is a 'upgrade to collectors edition' option, but that's not available until the game comes out it seems! Bah
You would play your account, the early-access code is independent from the game registration code.
But still, it is a lot of money just to get a small artbook, a 6 songs soundtrack, a security token, some postcards, a fancy but awesome looking box, a bluray documentary, 2 extra days, 6 bonus items and basically an extra game registration for a new account.
Wait, when putting it that way, it seems like a lot of stuff. Still expensive tho.
