Guard break:
Few second stun, you can pretty much go to the other side of the cabinet laugh at your opponent, go back and then do a combo even if youre no ninja. No other effects that I noticed. Guard break -> stun -> full guard bar again
Characters unplayable at location test: Roa, Twins, V.Akiha, Nero
Generally it seems ALL 2/5A attacks have been modified and most attacks seem to have shorter range.
Whiff-cancels looked alot less effective and didnt look to really give that mush of advantage anymore.
Warc:
Has a new attack that looks like Mystic Eyes. Effect unknown, was spammed by one player but had short range(EX-version as well) but got blocked once as well. It looks quite evil though :3
Old basic bnb works fine.
Kohaku:
Can throw small knifes.
5C seems to be able to be split into multiple parts. Shaft-stab, then spin. So if it whifs recovery time isnt too great.
jB range and animation remade, much shorter range.
Seems to have a counter-attack where she opens the sheat of her broom quickly and it blings.
5B gimped. 2A gimped.
Aoko:
Full-screen beam missile, animation looked crap but was fast and looked very annoying.
Ciel:
Has a new move, lookes like nanayas 236A/B/C and the whole crowd laughed at it when they saw it

Can throw three black keys up into the air.
Seems to have some wierd EX-move that lookes like it starts of like her bunker and then adds a few hits.
V.Sion:
Summons looks like spiderweb, so now we have spidergirl in the cast! /cheer
Midscreen summons, as well as something that looked like a feint midscreen summon that also hit.
6B overhead had a totally new animation with a backflip and it looked quite cool.
Sion:
214C does not grab anything that is not blocking anywhere on the damn screen. Same goes for the rest of the 214-attacks.
