With the talk of developers being sparse for content due to the fact that it was impossible to make money making titles for the Wii U due to low sales, I'm surprised they haven't come out with something new already. No doubt something is in development, but they're probably being a bit cautious so as not to put out yet another disastrous product. Gimmicky hardware isn't going to cut it for a game system, you've got to have the titles or there's no reason for people to buy. The Wii that is in so many homes right now is likely sufficient and is a factor in why a large percentage of those homes did not step up to a U. It used to be the sort of thing that younger kids wanted so it was a hot item at Christmas, but that target audience all have tablets and phones now, so the market for a cheap casual gaming system is also significantly reduced.
