I'm disappointed by this article since I'd really expect more from the Wall Street Journal. Of course they got the facts right, but their reasoning actually bases on one Japanese mum with two sons of which one prefers to play the PSP over the Wii.
Also, the mentioning of currency influences for worldwide profits is a little suspicious because they aren't mentioning the number of Wii's sold in NA during march to have a comparation with the number of Wii's sold in Japan, or that Wii's sales are massively increasing year over year in NA. Because of this the article sounds a bit fanboyish to me, but I'm probably overreacting.
However, as others have said, the main reason for the Wii's slumb in Japan is the lack of new software since christmas, and Monster Hunter is surely going to secure a fine lead over the PS3 for the upcoming months. I'm glad though that Nintendo isn't happy with AC's and Wii Music's sales (although I think AC did fine, as long as you aren't comparing it to the DS version).
