At least 20 million Wii MotionPlus sold in 2009

I think that's a little too ambitious to assume WSR will sell on par with Wii Fit. I'm not saying it won't sell well, but I think saying it'll outsell it by that much is wishful thinking. You might be right, tho.

The only way I see WM+ selling that much is if they bundle it like Squil suggests.
