God no, last thing Wii needs is more shitty gimmick games that have nothing other than the control scheme to move units. Developers haven't even learned to use the regular Wiimote properly, yet. Once they master that, then we'll talk about this new one.
Really though, I think the best way to go about something like this at first would be to impliment sections of games that use it. This is something that I think would start off cool, and just get boring after a while "Ok, I want to sit down and play now, but I can't, I have to stand here bobbing around like a bafoon". Having short segments in games utilizing this technology would allow the notion to stay fresh and fun, without becoming tedious and overwhelming.
