Call me crazy - but I have faith we'll one day have a spinoff game to The Wonderful 101. Not a full sequel, but an eshop game.
But I really only say that because I think Project Giant Robot would be excellent if you made it a game where you played as GEATHJERK conquering Earth and other planets around the Galaxy.
Overall, I think Nintendo tends to be pretty generous with sequels - even when the IP doesn't sell that well. It's the third party games faded into memory that make me sad.
I predict NX launches in 2017 - not 2016
