Popped into the store where I preordered to ask what was up. Apparently the system says release date was yesterday, but they couldn't see any evidence that it actually exists anywhere. They tried to call head office or the magical EB fairies or whoever to get some real answers, but were on hold for about twenty minutes and said they'd call me after they get through.

Edit: supposedly they are en route to stores as we speak. So hopefully they'll be appearing over the next couple of days.
