I predict:
8/10 to 8.5/10 from the critics to play the rate for what it is
7/10 from the Wii critics who can't rate the game for what it is, and have to keep it a notch below MKWii to save face
5/10 from haters who only want to see yet another Sonic game receive a low score
As for this:
Non fixed frame rate, gimped battle system, poor character and track selection...
Frame rate is not final. Battle system worked great during the demo. Character selection is leaps and bounds better than SST and pleases me. The track selection is the one are I agree with you. A Space Channel 5, NiGHTS and OutRun or Daytona track would make it near perfect.
