Balance Board = Very well defined and clever add-on = Huge success, despite not so many games for it (And the same could happen to MS, if it avoids shoveling it with Wii rip-offs and it keeps original instead).
WM Plus = Afterthought (although a clever one) = Moderate success with few games, but Nintendo couldn't really hope for more (And the same will maybe apply to PS Move, unless Sony does everything right from marketing to games line-up choice).
As XB360 and PS3 overpricing at launch allowed Nintendo to apply a launch price $50 higher than initially planned, it should have included WM Plus functions since the beginning.
