Sega has filed for a new trademark for something called "Sonic Gems Collection". Could this be another Sonic Mega Collection? There are a few Sonic games that haven't been released on a compilation disc yet, although most of them were worth skipping the first time around. Sonic CD is probably the most infamous unreleased game mainly because it was supposed to be a part of Mega Collection but was removed before release due to emulation issues. Knuckles Chaotix from the 32X days is another name that gets tossed around a lot, but typically during conservations about some of the worst Sega games ever made. Is there a demand out there for revivals of Sonic R, Sonic Shuffle, or Sonic Jam's 3D features? No word on what console this title is going to land on just yet.
