Sonic Team's unannounced Sonic game
Is anyone else curious? Since Sonic Boom is the last of the three exclusive Sonic games for Nintendo platforms, I would expect the series to make the jump to PS4 and Xbox One, with Sonic Team's unannounced Sonic game. They only said it would "use the traditional look and mechanics of the series".
Personally, I want Sega to use the opportunity to announce Sonic Adventure 3 but they've probably moved on from that already. I was just disappointed when they revealed Sonic Boom -- the character designs looked stupid and the graphics do not compliment them at all. Thankfully, it was not Sonic Team's game.
