I think Nintendo is feverishly working on coming up with something. They have a good track record, with not only Wii Sports but also games like Animal Crossing, NSMB, Wii Fit, Tetris and others. My money would be on them, though a third party may come up with something really innovative and make millions.

Tetris was made by Nintendo?

Published, propogated by and packaged with the original Gameboy.  It was the casual craze of its day.
