We have just received an update on what is in the proposed Sonic compilation disc for the Dreamcast. It looks like all the Sonic Team made Sonic games will be in there, meaning Sonic 3D Blast and Sonic R are out. However, this could mean that we would see Sonic 1, 2, 3, and Knuckles, in addition to Sonic CD! It also looks like the Sonic Team will be trying to put the late Sonic X-Treme on the disc as well! As you may know, Sonic X-Treme, though not made by the Team themselves, was developed by STI (a division of SOA) as a Sonic platformer for the Saturn. Development was then cancelled for unknown reasons.
We also have word that this new compilation CD, to be released in 2001, would span two GD-ROMs. As for extras, we have no idea what will be included yet.
