I don't need that much for the next Sonic game in terms of plot, but I just hope they do one of two things.
A. Establish, explain, and explore the Two Worlds thing Takashi Iizuka came up with (i.e. how do Sonic and his friends get from world to world? What is the name of Sonic's world? How can Angel Island be in both worlds?)
B. Debunk it, and confirm that the whole series takes place on Earth, with South Island acting as the "cartoony" Sonic place, and the rest of the planet being home to more realistic settings.
