I agree that price isn't really the issue, but that's a silly reason. The Basic version sucks--most people who want a Wii U want the Premium bundle. Therefore, while the more expensive version is selling more, it still means that the version that people actually want isn't selling well.
Could I trouble you for some maple syrup to go with the plate of roffles you just served up?
