i bet some dumper's gonna be stingy and release it only on the proper day (22)
Maybe
Some games are dumped even two weeks before they reach stores. This time, it's exactly the opposite. The game is already on sale in many stores and there's no dump. I guess that the dump is been holding back till the proper day. This way Nintendo isn't so affected by piracy and everybody starts playing the English version at the same time (excluding Canada, where many people already bought it).
