Ah f*ck it. I'm totally wrong about Wii Fit and I'll admit it.

It'll probably sell huge in North America. It still is expensive and sounds boring as hell to me but if the mainstream thought like me Miley Cyrus wouldn't have a career and Starbucks would have never gotten off the ground.
Nintendo will probably reveal their next "Wii _____" game soon and I'll wager it will require the use of some special peripheral. With this and stuff like Guitar Hero it appears the market is very willing to buy games that require speciality controllers despite higher prices. Might as well go for it while they can.
Funny how the remote was designed because controllers were supposedly too intimidating and here with the Wii they sell remotes, nunchuks, classic controllers, the zapper and now this board (on top of supporting Cube controllers) and the non-gamers that were supposed to be easily confused are eating it up.
