For those interested, KOF XIII is under development. SNK's Japanese site has updated some information on the game which you can find here:
Once it loads, click on the characters tab. This screen gives you a preview of what I'm assuming to be the game's OST alongside the long awaited return of team specific themes. KOF XI arguably had this, but it looks like SNK is returning to the true music feel from the 94-98 years.
Just select a team, and take a listen.
