I'm gonna say no, for one reason.
1. Money
The last Mario Kart for the Wii sold a bajillion, why would Nintendo want to split the revenue of Mario Kart with Sega?
But speaking of Sega, I would guess that this means we will see Sonic returning in Smash.
As for third game? Hmm I'm hoping for an RPG.
I mean they had that Sonic RPG, then you have the Paper Mario games. Make a Sonic/Mario RPG
