so to get this straight, when xbox and sony were beating nintendo, it was funny because nintendo was a failed company. now when nintendo is absolutely dominating them for going on two years straight, it doesn't really matter because nintendo is a different market than they are. gotcha.
as others have said... publishers have generally ignored the Wii. Month in and month out Wii has had the highest sales (often by a huge margin) for over a year now, yet pubs continue to play it coy. something tells me on the back of March (SSBB), April (MKWii), and May (WiiFit), publishers will take a new and aggressive look at Wii. There's no way a system can outsell it's two other competitors by as large a margin as Wii did this month and likely will the next two months without your shareholders asking why exactly you aren't giving it any kind of attention.
