During a "Sonic Fan Thanksgiving 2014" event at Tokyo Joypolis, Lead producer Takashi Iizuka took the stage to announced an upcoming game from the Sonic team entitled Sonic Runners.

Despite this announcement not much information was given aside from it being in development for smartphones; and based on the title one can assume it's a runner game. More information was promised to come in January.

Sonic Runners is set to launch in Japan in 2015, after that it will make its way to the West at a later date.
