Not that I'm out looking for DS fanart, but I do get what you're saying. I also get Spinosaurus is saying. Essentially, it comes down to the fact that Darkstalkers is an obscure series that ended in the late 90's, but has a cult following just large enough to keep it from being totally forgotten.
The fact of the matter is, a lot of people aren't going to know about it unless a new iteration is made. I know that Darkstalkers Ressurection is going to be a litmus test to see if there's enough demand for a Darkstalkers 4 (why do I find saying that weird? Probably because I never call Vampire Savior "Darkstalkers 3" I'm hoping DS4, if made, will have some kind of creative title). I'm going to get it, mostly because it treats Vampire Hunter and Vampire Savior as two separate arcade releases, as opposed to the past collections that just ports everything into Savior's engine, thus losing some of its aesthetic appeal (VH BGs aren't used, character select portraits aren't used, missing some unique sprite animations, endings are low quality videos instead of running at real time, etc).
Heck, even playing "Vampire Hunter" under Savior's engine feels wrong. I like Savior overall, but when I'm used to certain moves having certain effects in Hunter, it just throws everything off. I can use Pyron in both, for example, but his EXs are totally ineffective in VS compared to VH. This isn't a deal breaking problem. I just can't be as showy as I like (and required EX victories to reach special stages are just harder with him in VS).
Anyway, though, I like the series, and I want to see more of it if it does the legacy any good. But sometimes, it's best to leave a franchise off on a good note, and if Savior can't be topped, then don't bother. I don't want a Sonic 4 of the Darkstalkers series. Another concern is that I loved how the characters in Darkstalkers followed the 12 prinicples of animation in their sprite forms. In order for the series to evolve, it's going to have to use 3D models, or spend a long long time doing HD 2D animations. And I'm pretty sure they won't spend any kind of money on that for Darkstalkers. Therefore, I'm worried of some of the charm will be lost in the transition.
