KOFXV:
He can't talk anything about KOF XV. Even if he wanted to, he don't know or see anything about the game, but maybe something will be announced in the next EVO, in this case EVO Japan. Apparently, this year we will have none or almost none information. All that can be said is that the game is being completely redone (no KOF XIV will be reused).
K9999:
About "the one replaced by Nameless", you can't talk about him at SNK at all, even if anyone wishes, for legal reasons. He claims it is safe to say that from now on, in any SNK game, he will never return.
Samurai Shodown Season 2:
Samurai Shodown season 2 will have many surprises.
More tidbits at the link and a video of the KOF98 Esaka stage IRL location with a visit to SNK's office.
