SEGA has stated that Sonic Boom is a branch of the Sonic universe (much like the Archie Comics) and is not replacing the usual Sonic Team modern Sonic stuff.
Oh good, wouldn't want to undo all their great work of the last decade... *rolls eyes so hard they end up in the next room*
So this is a developer other than Sonic Team?
Can't find any games by Big Red Button entertainment, is this their first title? Looks like it's made up from ex-Naughty Dog devs, which isn't a bad sign at all. Since it's not Sonic Team, I'm actually more positive this might turn out alright.
I still think the character designs are weird. Not necessarily bad, but I wonder why they would change Sonic's SHOES of all things to be covered in bandages. I mean, it's probably his most iconic feature!
