Switch Mario Tennis and motion controls??

I was randomly thinking about this game, the fact I'm personally not that interested...then it occurred to me it will most likely use motion controls!
Detached Joy Cons and actually swinging, like the Wii days but better controls instead of waggle. I'm suddenly VERY interested in this game
Anyone else feel the same?

Any help appreciated.

I didn't find the right solution from the Internet.
