Saw a post about this over on SpekSNK that the arcade game Lord of Vermillion II will be featuring a collaboration with SNKPlaymore to use some of the King of Fighters (98) characters.
So far i can only find information regarding Kyo Kusanagi and Iori Yagami being in the game.
There was actually quite alot of coverage of LoV a while back in Arcadia but i never paid much attention to it due to it being a Japanese arcade only game.
From what little i know of it i believe it is some kind of card battle game where you place physical cards over a touch screen. I think when you finish your game it gives you a random card so i can imagine it must be pretty addictive.
It's kind of funny seeing SNKP using their characters in other games, just a shame that none of those games are fighting games.
