As promised, Sonic Team announced their next Sonic the Hedgehog game during the Sonic 25th Anniversary Party. The untitled game is known internally as Project Sonic, and a short trailer was revealed during the Comic-Con event.
We didn’t learn much about the game, but the video did show Sonic dashing through a post-apocalyptic landscape where he was eventually joined by “Classic Sonic” from Sonic Generations, so we might be looking at a sequel to that game.
Sega promised to announce additional information about Project Sonic “at a later date,” but for now, they’ve confirmed it’ll be released for the PC, PS4, Xbox One, and Nintendo’s upcoming NX console during the 2017 holiday season.
