Running rings around the (lost) world

During the last Nintendo Direct broadcast, it was revealed that Nintendo had entered into an exclusive deal with Sega to publish a series of Sonic titles. More recently, Nintendo Germany has stated that the trio of games will all be available this year.

Here's the portion of the press release in question, translated from German by a forum member over at Sonic Stadium:

Today, they (Sega) revealed further details of the second of three titles, which the two companies will release exclusively on Wii U and 3DS. All three games will be released this year.

We already know about Sonic Lost World and Mario & Sonic at the Sochi 2014 Olympic Winter Games, so what is this mystery third title? Could we be seeing a Sonic-themed Mario Kart helping, as was hinted at by Sumo Digital Executive Producer Steve Lycett?

We're sure you've got your own ideas, so why not let us know in the comments section below?
