I can't fathom how people could expect it to be much more than it was (hardware-wise). I understand the disappointment that Sega didn't include a new VDP to expand the color palette, but what else could you possibly (and realistically) want out of it? I mean the Turbo CD was just a CD drive with a limited amount of RAM and one added PCM sound channel. The Sega CD has its own CPU, faster than the Genesis's, and with the ability to use both. It has twice as much RAM as the Turbo Duo / Super CD, and several times more than the original CD-ROM2. It has a sound chip with 8 PCM sound channels (separate from the ability to play CD audio), which works in tandem with the two Genesis sound chips. And it has scaling and rotation effects significantly more advanced than the SNES's Mode 7. They really covered everything except the color palette. Some might argue for a faster drive speed, but that's really not realistic given the time frame, and not very necessary considering most of the games that came out for it.
