Managed to snag one from the gamestop I mentioned last night. It turns out that they just didn't put a sign up because of the leaked email. Guy said he figured people were going to line up regardless. They got three for today (another store in the area got six, while yet another got none), and all of them (including mine) were gone within minutes since another guy and I were already waiting and somebody else came in immediately after we were let in. According to the manager, they (as in gamestop as a whole) are supposed to be selling more tomorrow, corroborating what the one guy said about hearing that Friday was the day he heard they'd be selling more. They had only received today's stock of NES's so far, so the guy didn't know if the next shipment was coming in today or if they'd be in tomorrow(and thus go on sale after they were processed, rather than when the store opened).
That said, I got there only 20 minutes before the store opened and there was only the one guy before me. We might be at the point were demand has tapered off enough to where you don't have to get to the store that early to get one now. Either way, tomorrow is another chance, so good luck to everyone else!
