Sad reading KOF XIII is not that popular in China. Looks like something similar happens in Mexico, where KOF XIII is in several arcades, but is always empty and people play 2002UM (from what some mexicans comment in speksnk forums). I'm starting to hate 2002UM..
Sad to see kofers and even SNKP, from what we see and what we read, don't bet for new re-birth of series. I know XIII has less characters and less command/special moves. But if people and snkp give an oportunity to the game I'm sure we could see an awesome KOF in a few time, with a lot of characters that now are missing (shingo, rock, vanessa, mary, billy, chang, choi, eiji, geese, etc) and new ones, more special moves, command moves, DMs, even new ones no ever seen in older kofs! new story, new teams, new bosses, news in gameplay... I think future could be full of news and great things in KOF world now that a new era has started. But without love for XIII... probably we won't see that awesome future for KOF, and people will play 2002UM eternally.
