well its been 36 hours since the price went back up, I think it is safe to assume that NDC continued to sell more yesterday than anything else. Cyber Monday's sales should no longer be in factored in (no way the lag is 12 hours).
I do not think it will keep number until the price goes back down. Once Sony starts advertising the Sunday price drop in more locations people will start to hold off on the 349 price point, especially the day before, most people can at least wait one day for a deal.
psn- tokila
add me, the more the merrier.
