Then having the Wii Plus like this would cause it to be eternally out of stock.

With such a feature, a number like that is undoubtly a flop. 

That would definately help the situation in Japan.. However if anything I'd see this happening in 2010.. Well at least more likely..

Why? Well Nintendo will most likely want to drop the price of Wii in 2010 and this will allow them to give consumers that option but also to continue selling at $250 with an upgraded console with more value which is what Nintendo would prefer.

Another reason is that Nintendo will want consistant growth and if they release Wii Motion Plus and Wii Sports Resort Q2/Q3 2009, Wii Fit Plus Q4 2009 and then Wii Plus Q2/Q3 2010 along side smaller games, maybe Starfox or Paper Mario with The Legend of Zelda Wii coming in Q4, it makes a lot more sense that way (not saying that's what'll happen but it's the way Nintendo will be thinking)

I like what you said for upgrades except for the wireless sensor bar - no point.. and the wireless nunchuk.. more batteries, and a strap would be needed for that too..

How about a Wii Remote Plus with a built in battery? That'd be more useful

Makes since to me.

Anyone going to get it? looooool nevermind I thought this thread was about Wii Motion Plus. But Nintendo will not release a new console. Just more games.

You don't know for sure!

Theory: Wii Plus Plus

There will probably be a Wii with hardware power comparable to the 360, but not sure when. They certainly won't take out those Gamecube slots though: One reason - BRAWL!!! Every serious brawler plays with the gamecube controller.

Advantages
Lots of cool shit, as mentioned

Disadvantages
GC games are no longer played with the comfiest controller in existance. Now played with one of the least comfy controllers.

Hmm, sounds like a Wii minus to me
