If the stores know what's up, they'll implement one set per person limits. If they have even more sense, they'll buy some with their own paychecks, and then resell them themselves online. I'm keen to pick one up at a local store because of nostalgia for making a motorised V-22 myself as a kid, but I can't really blame people who will want to pick up multiples and make a profit. It's kinda a historic set now, being both the first (and last) officially licensed Lego "war" set, and exceptionally rare.
