RUMOR: More info on Nintendo x SEGA - 3rd Sonic game is a racing game staring Nintendo crew, Deal may extend to other non Sonic SEGA games and expect Sonic and Bayonetta in Smash.

IF Mario Kart can't be ready for Christmas, perhaps Nintendo went to Sega and started prepping a crossover game based on the Sonic Transformed engine with other Nintendo characters put into the game.

I could see that. Something like that probably could be rushed out in time for Christmas also.

Yes, but if it gets rushed, that also implies that they didn't spend enough time making it and polishing it, meaning that it likely would also wind up not be a very good game......
