That was a different situation. S3&K has been ported to almost every system under the sun. CD only had 3 releases: Original Sega CD, Windows 95/98 port, and Gems Collection. It was difficult to port, and when they saw Taxman's PoC, they realized he had saved him the work of doing it themselves. S3&K doesn't have those things going for it. Genesis/MD emulation is a walk in the park nowadays, 1/2/3 have saturated the market before, with the added misfortune of S3&K selling significantly less than the other two. Not saying any of these reasons are good reasons for Sega not to take the plunge, but they have a myriad of rationales they could employ as to why they won't. On the plus side, Taxman's work has provided the best iterations of 3 classic Sonic games, and has opened up doors for him to work on his own IP's and non-Sonic projects, which has me pretty pumped. I'd say that's a pretty good consolation at the end of the day.
