What I find surprising is that they'd need to. Wii came out in, what, 2007? At the time, I believe I read that Nintendo was selling the units at a profit on the hardware itself. If true, I'd think that four years down the road, the costs of a redesign would easily outweigh any potential benefits....especially since they have a new console announced and the vast majority of the Wii consoles that they will sell already have been sold.
