As I said on the main page news posting:
It’s hilarious that fans will complain about Dimps, yet Sonic Team has brought us Heroes, Shadow and ‘06. Of course, it could very well be a collaboration of Dimps and Sonic Team members that brought us the HD Unleashed, and even then consider how few (if any) Sonic Team memebers remain from the glory days. With Takashi Iizuka the rumored director, there’s no telling what sort of team is behind Sonic 4.
