At the beginning of the month SNK playmore registered a new trademark for "KOF" with the Japanese Patent and Trademark office. It was filed under class 9 (video games), 28 (accessories and parts for video game machines) and 41 (online games).

SNK already had a "KOF" trademark registered, but it was bound to an old logo. Yet, it's expiration far in the future (2018) so this isn't a renewal of that one, and is probably for something entirely new.

Considering the recent trends of releasing sequels and reboots of popular franchises using only acronyms as the title, it's quite likely that we're looking at that kind of possibility.

The recent announcement of the mobile game The Rhythm of Fighters may have left fans a little disgruntled, but if this indicates a new King of Fighters game in development, it could save the day, especially since the trademark makes no mention of mobile platforms.
