My parents bought a Wii. I think the last system they even played was Atari 2600. They rarely play their Wii these days. There was a time when they would have their friends over and they would all play Wii Sports or whatever, but that was years ago now. They played with my Kinect a couple of Christmases ago and enjoyed it, but not enough to go out and buy it.
They would NEVER buy a Wii U. The benefit or even a distinction from the Wii just isn't there for them. In this sense, I agree with Pachter.
I also think it was a mistake to have the system look so similar to the Wii. Looking at the commercial, I think the average person would be confused about the Wii U. Is it just a controller I buy for my Wii? Is it a handheld system? etc.
