Not to be on Sega's nuts or anything, but I honestly don't mind revisiting the old zones for the entirety of Sonic 4. I just think it needs to be expressly said that the game is, in fact a revisit of the old locales. Then we could speculate at what zones would be in the next episode. Speaking of, there better not be a huge gap between episodes. I could deal with six months. A year or more is pushing it. I just wanna play all of Sonic 4 from start to finish already.
