Who wants to bet that Million would be complaining about Nintendo "Milking" their customers if Miyamoto said he was working on several add-ons to be announced next year?
The truth is that there is still lots that can be done with the Wiimote, even more can be done with the Wii MotionPlus and the Wii Fit Balance Board. Over the next 24 to 30 months Nintendo will (probably) have to release a version of every game they have already released with advanced controlls to make Nintendo fans happy, there are several games that haven't been released yet this generation that they will have to produce, and they (probably) have dozens of new games that are in the works.
If Nintendo did have an idea for another peripheral they (most likely) wouldn't be announcing it until 2010 and at that point the question is whether they would release it with the Wii or their next console.
