The sega CD while not the best seller wasn't a brand doomer. The CD has its place in history, however the decline began with the 32X and Nomad as both weren't heavily supported.
Then upsetting the retail chain by releasing the Saturn 6 months early with only 2 launch titles vs the 15 or so it would have had in its original launch is what spelled doom for sega's branding. Not releasing a Sonic title (even if it was a 2D sidescroller) was also a giant mistake. The PS1 was a perfect storm but sega may have eaked out a nice niche in the 2D diehards and Japanese game enthusiasts with a better release policy for the saturn.
Also a single processor architecture would have been much better from a programming and cost enivornment.
