Just a theory on the Wii, but maybe Nintendo diverted a bunch from the US to Japan to coincide with the Wii Fit launch. They have to shuffle around a fixed amount of consoles, so they're juggling the holidays here and in the rest of the world and a major launch in title in Japan. They put a lot of advertising and effort into Wii Fit in Japan.
Just my thoughts, because the WW sales from last week and this week look pretty even.
