The game is developed by Sega of America in collaboration with PagodaWest Games. Christian Whitehead and Simon Thomley, the people behind the remastered Sonic ports on mobile devices, are also helping with development. Sonic Team head Takashi Iizuka says that we'll learn more about the game later this year.
Sonic Mania releases for PS4, Xbox One, and PC in spring 2017.
The second announcement was a new adventure helmed by the Sonic Team that features both classic and modern versions of Sonic, much like 2011's Sonic Generations. No title has been revealed, but we do know that it's coming holiday 2017 on PS4, Xbox One, and the Nintendo NX.
On top of all this, Sega made two additional announcements. Mobile game Sonic Dash has passed 200 million downloads and will receive a special in-game event that adds the Green Hill Zone and Classic Sonic as a playable character. The event only lasts a week, but players can unlock both the classic level and character for use after the event. Its available on iOS, Android, Amazon, and Windows Phone devices.
The animated Sonic Boom series' second season was also announced, and party attendees were given a sneak peak at what Season 2 has in store. We'll learn more at a later date. The next Sonic Boom video game, Fire & Ice, is set to release September 27 exclusively on 3DS.
