Yay... GW2 Despatched!

Just got back from work and was quite surprised to see that Amazon has dispatched my pre-order/purchase standard edition of GW2. It says it will arrive tomorrow so at least I will get to register and install before the 28th. I still can't find much with reference to the 1 day head start and if that is pre-order or pre-purchase, or indeed, what the difference is. Well I'm not complaining I'm very excited and will continue to read as much useful and useless information over the weekend. Good luck to those of you that are starting tomorrow and see (some of you) soon!
