I'm not really sure what you were expecting here? a new full retail release? a brand new game? a giant kyo pinata?
Actually, I was expecting something along the lines of a KOF 20th Anniversary artbook. It wouldn't be that hard to do. Just take the KOF 10th anniversary artbook, add in illustrations, screenshots and sketches from KOF XI, XII, XIII, and numerous spin-offs like Maximum Impact 2, KOF '98 Ultimate Match, KOF '02 Unlimited Match, KOF Sky Stage, and so forth. Toss in some artwork from Fatal Fury (the original King Of Fighters), interviews with a few developers and illustrators, a handful of original illustrations and a brand-new cover and voila- instant artbook!
A few of the recent news threads have amused me, since a few years ago, I posted a poll asking what direction SNK Playmore would be heading in over the next few years. One of the choices was, "Nope. They're done. It's all pachislot and cell-phone games from here on out." Now, I can't recall how many people voted on that entry, but those that did may be psychic (or at least able to read the writing on the wall).
Now, I'm not quite ready to give up completely on SNKP (since all it takes is one good new game to turn things around), but I can't help but think that over the past five-odd years, SNKP has become the company Aruze originally wanted them to be.
