Rumor: Sonic All-Stars vs Mario Kart?

Today Sega has announced that they will be publishing and distribution three Sonic the Hedgehog titles exclusively to Nintendo systems.

This deal with Nintendo includes Sonic Lost World, Mario & Sonic at the Sochi 2014 Olympic Winter Games and other unannounced game.

Steve Lycett, executive Producer at Sumo Digital (developers of the Sonic All Racing IP)  may have dropped the bomb last month. In April, he twitted some interesting stuff. In fact it’s not just interesting, it’s very interesting:

Could this “unannounced -only for Nintendo- title” be a Mario Kart x Sonic-All Stars crossover? Is Sumo Digital working with Nintendo in a new Mario Kart game?

Of course, this is a matter of conjecture, but this tweet is very intriguing due to the agreement reached between Nintendo and Sega.

Thanks, Nirolak.
