From Gamasutra:

Analysts have explained a possible reason for the low Wii sales this January. Japans Wii Fit and Brawl sales may have a lot to do with it. The small lead over the PS3 is likely due to “the diversion of Wii units to Japan to support the launches of Wii Fit and Super Smash Brothers Brawl.” according to one analyst.

Either way, the PS3 sales are picking up. The 360 is lagging far behind, but Microsoft had an explanation for that. No idea who to believe at this point, but hey, that’s the way sales works.
