Sonic Team hinted a while back that there was a new Sonic project in the works. Currently called Project Sonic 2017, a trailer has appeared showing a dystopian world under attack and not one, but two blue blurs leaping into action.
Though Sonic Team never actually said anything about it being the next Generations game, with new and old-school Sonic present, what else could it be? A small part of the trailer demonstrates Sonic running in what seems to be a 2-dimensional side-scrolling segment, possibly a small taste of gameplay.
The new Sonic game is set for holiday 2017 on Xbox One, PC, PS4, and Nintendo NX.
