A Wii Sports Resort sequel for Wii U makes a good deal of sense to me. It's the one big franchise from the Wii Nintendo really hasn't attempted on the U.
In terms of gameplay, Nintendo could offer more variety than the original Sports Resort buying utilizing the Gamepad, the Fit Meter, and NFC.
In terms of sales, it's a title known and loved by the "blue ocean".
Overall, I think it works better in the Wii U "formula" than Wii Fit and Wii Sports. We expect Wii Sports to always remain Wii Sports -- even when it's on Wii U. No one wants to fling the GamePad into the TV playing Wii Tennis or bowling. Wii Fit obviously shoe-horns itself into the expectation to make its users significantly more fit -- which it has some difficulty in actually doing purely on its own. Wii Sports Resort is a genuinely more easy-going, party/casual game. It better lends itself towards weird little mini games with all the Wii U peripherals because of these expectations.
However, it's always been a good game you could use to break a quick sweat if you really wanted to. I'd wager it'd be a good avenue towards introducing the Quality of Life platform.
I believe it would outsell Wii Party U at the minimum.
What do you think? I for one wouldn't be surprised to see it at E3 this year. Yet to this point, no one has talked about that possibility at all. Discuss.
I predict NX launches in 2017 - not 2016
