We shouldn't compare Wii U with Wii; we should compare it to PS360 instead. Wii was a phenomena, and was on track to outsell the PS2, but never truly could do this in the end. But it sold at a record breaking pace the first few years.
How does Wii U stagger up to PS360?

Furthermore, I think VGChartz should add a "Like"-button.
