Are Wii sales starting to fall off in Americas and Others as well as Japan?

[BTFeather55]

It does seem that the Wii has fallen off a little since the middle of January. Maybe it was still running on a holiday lift then, but it was at over 500,000 then and less than 300,000 last week (but that could be explained by people wanting to get the new DSi's instead -- since it sold over 600,000 copies).
