Haha, pretty sure that's a fan-made roster. Though that roster ain't bad, the addition of all the Paper Mario partners and Koopalings seems a bit over the top.
Definitely a fan made roster. Not that I wouldn't like said roster, it'd at least be better than seeing just Honey Queen again and Metal Mario again like Mario Kart 7 and would definitely add some interesting characters to the list.
35 characters that i definitly don't see in MKU are here... the Paper mario characters, kritter, king k rool, baby rosalina and waluigi (baby waluigi will only happen if the creators of Mario Tennis, who made Waluigi will make a baby waluigi i think..) Wario characters, ROB, Wart and other old forgotten mario characters wont make it.
i would love it if the koopalings would be playable, but i only expect Boom Boom to be playable from the boss enemies
I doubt another Mario Kart series would be released any time soon. And you could forget Nintendo adding characters from Paper Mario if it does happen.

It's possible
I don't know. There are three glitches (I don't know if the other two was fix, but I know one of them was found recently) in the game right now. Nintendo's priority with Mario Kart is probably fixing up those glitches for smoother gameplay while playing on multiplayer. Let's say that all the glitches, that I know of, are fixed, Nintendo would take a longer with the game so they can make sure they can avoid the problems they faced when they released MK7. I'm not saying your theory is incorrect; however, I think there is a low possiblity due to the problem with the glitches.
well we will just have to wait and see ya know maybe nintendo is putting paper characters as a costume or somthing i wouldent mind being able to have a bunch of nintendo characters in it like super smash bros
