Game developer and publisher SEGA have teased an announcement of some kind on their Twitter account. It could be a new Sonic game or other SEGA title coming to various platforms. It is worth noting that SEGA also has a hand in the Bayonetta Games, so maybe we could see something Bayonetta 3 related? Who knows? I guess we will find out soon enough.
SEGA is teasing something for January 16th.
