We know that Sega has a year of celebrations planned to mark Sonic the Hedgehog's 25th birthday, but aside from merchandising deals and the like, it's still unknown if we'll be getting a fresh Sonic video game to mark the momentous occasion (and no, we don't consider the previously-confirmed Sonic Boom: Fire & Ice to be that game).
However, we might not have to wait that long to find out what's happening, if the Sonic Tumblr account is anything to go by. The post shows Denver Broncos player C.J. Anderson clad in a Sonic shirt, but it's the tags which are arguably more interesting:
#we have something coming up in February that some of you will be interested in... #but we can't talk about it yet! #don't tell anyone you saw this hint in the tumblr tags - okay?
Could this be a tease of as new game? Let us know what you think by posting a comment.
