It appears that Sega are bringing Sonic to the PlayStation 4 and Xbox One based on a sign they had at the Nuremberg International Toy Fair.
This year Sega attended the International Toy Fair to show off some new Sonic merchandise and to promote the upcoming Sonic Boom cartoon that is coming to Cartoon Network later this year. A member of the number one German Sonic fansite managed to get a quick photo of the below image which shows a sign that quite clearly says there’s an untitled Sonic game headed for the Wii U, Xbox One and PlayStation 4.
Sega have yet to comment on this but there’s no real reason to believe this is a hoax. Perhaps we will hear more in the next few months or maybe at E3?
