What do you think the next sonic game will be?

So, Sega has announced a new sonic game! (the one that's not Sonic Boom/Jump Fever)
What does everyone think its gonna be? And what do you want it to be?
Personally I don't really mind what the game is going to be, I hope there will be a PC release of it.

Leave a comment on what you think. :3

It could be...

Sonic 4 Episode III
Sonic Colo- wait, that line is exclusive to Nintendo.
Sonic Adventure 9001 (seriously I'm unsure if Heroes, 06 or Unleashed were Adventure 3).
Sonic & All Stars Racing Transformed sequel.

I'm not gonna speculate at this point. I would rather wait until more details are released.

I hope they bring in more playable characters other than Sonic, but doubtful.

Can't find that announcement anywhere so I'm pretty clueless on this. Nonetheless, if it's not exclusive to Nintendo this time then maybe another reboot like 06. They left off Ps3 and 360 with Generations right? It'd be a good timing, I guess
