I'm starting to think Sonic '17 will be like a modern version of Sonic CD.

Classic Sonic will take the "Past" stages while Modern Sonic takes the "Bad Future" stages. Whenever Classic Sonic has to assure Modern Sonic gets the "Good Futures" or not I'm uncertain.

My theory is Modern Sonic (from the original timeline) and Classic Sonic (from Sonic Mania in the altered timeline) are seperate characters as depicted in the trailer. But it could be possible Sonic could physically switch from Classic to Modern self if he will be moving to specific points in time.

That is to say if Dr. Eggman will have the Death Egg mk.II in Sonic '17.
