Looks like SNK is leaking again, huh? Guess I don't have to feel guilty about sharing this.

Game is still 2 vs 2, this time with assists. Your assist's special is chosen on the select screen like in MVC. You can get "happy birthdayed" too so don't spam your assist. Every character has a "V-Trigger" like in SFV that powers them up temporarily. Kyo gets EX specials, Iori goes orochi, Geese gets his boss moves, Haohmaru enters concentaration one state and Genjuro enters rage mode.
Game uses an anime aesthetic instead of the realistic style from XIV. A good comparison would be that J Stars game on PS3 and PS Vita. Story mode is similar to SFV and MVC Infinite in terms of style and presentation.
Expect an announcement at Playstation Experience and a release some time around Summer 2018. There will be a DLC season pass with four characters and six costumes because SNK saw how successful this strategy was for other FG devs. I do not know
who these characters are or who the costumse are for.
For character stuff, Kyo is based on the Ash saga in both design and gameplay. He has both the fireball and rekka, including the new rekka chains from XIV. Instead of RED Kick he has the rising kick.
Iori uses the XII design but has his usual fire gameplay.
Ryo's design takes some elements from the 3D Fatal Fury Wild Ambition by giving him some stubble and removing his gi top.
Robert is the same as the last game but with an XIV styled goatee.
K' and Kula have new designs that make them look older, K' in particular wears a black trenchcoat and his intro has him throwing away a cigarette.
Mizuchi looks very different with scars and veins that seem to imply that the orochi power is overwhelming his body. His "V-Trigger" turns him into his boss form, with an animation that looks like he's in a lot of pain.
Goodman's playable version is closer to a puppet character like SFV's Menat, with the ability to position his ghost on screen and pressure with it.
The new boss is the leader of a terrorist hacking group trying to overthrow the world governments by obtaining the powers and techniques of all the Neo Geo characters. In the final boss fight he wears a suit that looks like a robotic gargoyle and uses various signature specials from the cast. He can also use techniques that kidnap your other character to prevent you from tagging, and when he kills one of your characters he brainwashes them to be his own personal assist. His ultimate is a transforming special like Yuki's, where he becomes the giant scythe wielding demon from Metal Slug 5.
In the story mode, Dr. Brown from World Heroes gathers the Neo Geo characters to assist Yuki and Ai's organization in the battle against the hacker's group, who have recruited a fallen Goodman and his corporation to their cause.
That's all you're getting for now. Be patient and wait for more details like good little boys and girls.
