Today has been a busy day for Sonic Mania news, although a lot of it was, unfortunately, due to leaks. However, there has been one official announcement from SEGA.

However, it seems today’s leaks have resulted in SEGA changing their plans. We’ve included the video down below, so feel free to check it out.
