Not sure if this has been brought up (not sure how many King of Fighters fans there are here), but the Art of Fighting team in KOF15 has been revealed to be Ryo, Robert, and King. The first two are mainstays, but I'm not sure how many people expected King (considering that she's usually on the Women Fighters Team, while the Art of Fighting team usually consists of Ryo, Robert, and either Yuri (Ryo's sister) or Takuma (Ryo's father)).
Glad to see they're changing things up. I play as Ryo a decent amount (at least when I play KOF98), but I'll have to try King to see what she's like. (by my understanding, Robert is like the Ken to Ryo's Ryu, so they shouldn't be too different)
It does leave me wondering who the Women Fighters Team is going to be - Yuri and Mai are almost certainly on there, but I guess it could be pretty much any woman who's been in KOF, such as Blue Mary, Alice from KOF14, May Lee, Kasumi Todoh, etc.
