So I just found out that the Koopalings are also going to be in this game, as well as Boom Boom and Bowser Jr.
Well crap, now it looks like I'm going to have to get it then.
Seriously, though, I am not excited at all for this game, and while I love the Koopalings, I feel like now they truly are back, and now I don't need another 2D sidscrolling platform with them as bosses. I'd like to see them in a 3D game or spin-off game, but after this, I feel like I'm officially done with any new Mario sidescrolling platformer Nintendo dishes out...
Unless it's like Super Mario Bros. 2. Or brings back the characters/enemies/bosses from those games. Then I'd be interested.
