The video has since been taken down and the stated release date is Summer 2017, but Twitter user Nibel screengrabbed it before it was spotted and taken down.
For a brief moment today there was a trailer on Sonic Mania’s Steam page that had the release date of August 15 in it.
This may not be a release date for all platforms, but August 15 would definitely classify as the Summer to most.
While we wait for confirmation, here’s the video to Jazzy Jeff and The Fresh Prince’s absolute banger Summertime.
