Considering MS said they had sold 17.7million consoles by December31 and we have them at 17.22million, that would place about 480k at stores, and that is assuming that they have shipped zero units this year. That sure is a big supply constraint 
Edit: I just checked Future shop online, its like best buy, and they have all models in stock except for the arcade, they also still have the christmas holiday bundle in stock.
