While this is unconfirmed, it appears we may have a release date for Sonic Mania. It was originally set for a spring 2017 release when it was announced during the summer.

Amazon has sent out an email to fans who have the game reserved that the release date has changed to June 2nd. This fits into the spring window, barely and is a Friday so it makes sense.

Here is a photo from the email Amazon is sending out. We are waiting on confirmation from Sega.
