It surprises me that Nintendo would think enough people would pay for this, but considering the tech in it, I doubt it could sell for cheaper at a profit. What people don’t realize is that there is a full on radar based health monitoring system in there that drives the price up. I expect this is a test bed for a future product that someone is trying to make back the R&D money.

Yes thank you! Edited my comment to correct it.

This sort of thing is already being done with many commercial devices. See www.powercast.com for one of the companies.
