I talked to TableTop just now, and they said that they have 3 sources and none of them indicate that they have shipped anything yet and they aren't expecting anything until next week. It seems possible they are going to get them sooner since one guy in Texas reported his FLGS had theirs already, but is seeming less likely. As such... I decided to take my chances with Amazon Prime. If it ships promptly like a few others have reported, I would have it by Friday maybe, and if it slips to Saturday, it might still work out if it comes early enough.
I'm down for playing some Adventures, and/or proxying a few cards if we don't manage to get a real copy, but hopefully we don't have to make that call.
