Hmm ok so onyl 55% of WFPlus sales are from Balance board.
That makes a gap of ~2.5 million to the BB surpass PS3.
It will definitely happen.
@theprrof
Those are cheap peripherals (rumble pack? LOOL for god's sake) and didn't got as much support as the balance board to be considered "platforms" on their own.
As for the dance pad I'm pretty sure it hadn't that stellar sales and the games it has might be all from the same company, not a variety of 3rd party support like the BB.
