I remember an OOOOOOOOOOOOOOOOOOOOOOOOLD trailer for SA that had trippy music playing in the back, and a little scene of knuckles doing some uppercut combo move while the camera moved around him. I don't remember much except it had Sonic running down the building from that one level, and Sonic on the Tornado when it was at night.
Anyways, maybe something from Knuckles's little uppercut thing will be discovered. And thats it. Or maybe the exact opposite, maybe we'll find so much shit that we'll have to rewrite Sonic history. Who really cares at this point?
