I pre-ordered everything from amazon.de (closest amazon to my country), but then my county's #1 online shop started putting up the books so I ordered them there instead. Then my FLGS announced they were doing pre-orders after all, and so I cancelled my order at the online shop and ordered at my FLGS. But I did keep my starter set pre-order along with my pre-order of everything at the FLGS, so I'll get two starter sets. This means I 1) am practically guaranteed to have it on release and 2) can give one away to new players.
This is the first time a new edition is released since I started playing D&D. I'm super excited about everything, and I want to buy every book despite knowing my group will not so easily leave 4e behind.
I can't wait!
