I'm not a fan of this kind of game, but I also wouldn't be that surprised to see Nintendo produce one ...
If I was in charge of Nintendo, in the wake of the Wii I would have focused on creating or buying development studios to create high quality "core" games (mostly) because you couldn't count on third party publishers to take your platform seriously. While it doesn't sound like a lot of games, if Nintendo added 3 to 6 games to their line-up every year it would make them far less dependent on third party publishers to attract certain gamers.
