During a livestream dedicated to the 25th anniversary of the Sonic franchise, Sega announced the real "Project Sonic 2017," which is a completely separate game from the retro-style Sonic Mania introduced earlier tonight.

The game will be a "brand new experience" by Sonic Team, coming Holiday 2017 for PS4, Xbox One, PC and Nintendo NX.

Nothing else was shared, including the final title of the game, but the trailer that you can see below is quite promising.
