Whoa, you look eerily similar to one of my brother's old friends who moved to Utah...
I called the Somersworth and they WILL be doing a midnight launch. I was under the impression that it needed to be a Wal-Mart Supercenter that stays open 24 hours in order to pick one up at midnight (I never even would have asked, I just assumed the Salem one was a 24 hour supercenter hence why you were going there). If your local mall is Fox Run, how is Salem the closest Wal-Mart to you?
To be honest, I'm still hoping to finagle a Wii out of my GS at 9 PM when they close. I cannot possibly imagine that breaking street date by a whole three hours will have any ramifications. By the time it would be possible to contact a Nintendo rep, it would be impossible to prove.
