It is entirely possible that this was spotted ages ago, and I simply happened to miss it. However...
I've just acquired the pc version of SADX, and was playing on it yesterday evening. Upon exiting Casinopolis, and seeing the little cutscene with the Ice Stone appearing in an alley, I noticed, as the camera panned back, a familiar-looking rabbit flying with her ears in the background. Couldn't see the face in that instant, but given Sonic Team's tendency to populate the streets with people rather than furries, surely this must have been a Cream cameo appearance?
