Based on what I know about Sakurai I would be very surprised if they did anyone other than Tails or Knuckles as playable. Shadow may be more popular but Sakurai doesn't always look at popularity, he looks at staples of the franchise. My personal feeling is that no other Sonic characters will be announced as playable. Though I hope I'm wrong because I'd love to be Tails.
