Some dismissed Sonic & SEGA All-Stars Racing as a SEGA-themed Mario Kart wannabe, but was obviously superior for including Shenmue protagonist Ryo Hazuki as a playable character (wait, what?). According to a new rumour, there could be a follow-up in the works at developer Sumo Digital.

The Sonic Stadium received a tip that claims the series is heading to 3DS and Wii U, with an anonymous insider source saying:

Now working on another title for Sega on 3DS, VITA and WiiU. [The] title we are working on is top secret but the last game we did for them was Sonic And Sega All-Star Racing, so the logical conclusion would be…

Sumo has a long heritage with SEGA, having worked on home conversions of Out Run 2 and original projects such as SEGA Superstars Tennis. What could the publisher-developer collaboration lead to next?
