While SEGA has remained vague about Sonic Mania’s release date, we may finally have an answer. Sonic Mania’s UK and German Steam pages’ new trailer ends with a confirmation of the release date: August 15 2017.
Unlike past release date leaks from retailers, this is almost certainly not a mere placeholder. So while the release date may still vary a little bit by platform and region, it seems that we finally have an idea of when Sonic Mania will be coming out. Currently, we only have confirmation that this trailer is up in UK and Germany, specifically. We have no confirmation from other European countries, though given how European releases tend to work it’s likely the date will be shared by the entire region. The US Steam page, meanwhile, still only says “Summer 2017”.
Stay tuned for further developments!
