To round off the SEGA stream for Sonic's 25th anniversary, a brand-new Sonic game was announced. It's (tenatively?) named Project Sonic, and will be available during Q4 2017. The game features both modern and classic Sonic forms, much like 2011's Sonic Generations. The trailer notes that Project Sonic will be made by the same team behind Sonic Colors and Sonic Generations. Interestingly, there will be an NX version of the game.
