Between beta tests and mobile ports, SNK has found some smart ways to keep the King of Fighters series active and up with current trends. A recent trademark filing may signal another twist, a bit odder than the rest.
The trademark (via Kotaku) is for game software called "The Rhythm of Fighters." It's too early to say for certain what this might be, and like all trademarks it may not ever become an actual product. But the name seems to imply ties to the King of Fighters series. And hey, fighters need a degree of rhythm, so it might not be as left-field as certain other series.
