Not to mention, if SNKP were to really put KOF98/98UM and KOF02UM on showcase for PSN (and other ports), SNKP is nearly guaranteed to benefit from this in the long run. Many faithful fighting game fans would go for titles such these and it would end up all being for a decent price.
At this point, if anything, I would rather just see CVS2 available - If a CVS3 were to come out, I don't think it would sit very well with both SNKP fans, especially with how Capcom has been conducting their management as of recent (hell, they might even give SNKP characters the poor treatment again! Back the first CVS, SNK characters at the time were missing a lot of moves... some of which happened to be SIGNATURE moves of the said characters. CVS2 was slightly better about it but it was still a bumpy road on SNK's side - due to the game being pretty well balanced for the most part, I even go as far as to utilize SNK characters exclusively on CVS2 - I agree with Tyrant - I don't wish to sound cynical but I'm not sure if I want to look forward to a CVS3 right now either).
