Are people really still recounting the jaundiced story of how Sony was going to help Nintendo make a Super CD attachment? And how that deal going south led to the Playstation? I'm sorry, but that's kinda sad.
For one thing, Sony approach Sega afterwards, and THEIR deal also went south, BEFORE the PSX finally came about.
Secondly, remember the Sega CD? It was pretty goddamn terrible, and outside of Sonic CD, I'm hard pressed to think of a single decent game for the damn thing. A "Super CD" would not have been a boon for SNES at all. Nintendo made other arrangements that obviously led the SNES still going strong in 1994-96 with some really great games, like DKC, Yoshi's Island, Killer Instinct, Kirby, Stunt Race FX, etc. And they managed this without any needless attachments and add-ons like Sega blundered their Genesis success away with.
Yes, the Playstation 1 was a great system. And yes, it was certainly popular. But people need to quit acting as if it was the first CD game console. The Turbo CD was. And then the Sega CD, and the 3DO, and the Sega Saturn (which by the way, was in many ways a better console than the PSX). The Playstation brand deserves it's respect and it's kudos, for sure. But, I'm sorry, Sony did not "create the industry", nor did Xbox "change the playing field".
