They still haven't even started taking pre-orders for the Collectors Edition in Europe yet.
It's not coming out anytime soon.
If you mean "Blizzard", then I guess you are correct - but neither has the US Blizzard store. Plenty of stores (quick search finds at least 10 Swedish stores, Amazon.de, etc...) are taking collector's edition pre-orders, though.
Doesn't seem to be on Amazon.co.uk, Game.co.uk or Gamestop.co.uk though :P
But yeah, you're best off just taking it easy and playing some of the other great games that have announced release dates, while waiting ;)
