Hello it's been awhile
from footage I've seen there are a few things that are hard to miss and I also have speculation
There's a short clip showcasing her tilts, specials, and a few normal (link here:
https://youtu.be/0yD_B4ZkdME). Tilts appear to be faster in start-up but the cool down looks more or less the same (subject to change as the character could change during development).
=========================
down B appears to be a parry type move instead of a counter or a reflector hinted that she strikes the same pose before using both moves (same pose as her current down b counter) , I speculate you will NOT get to chose which one you get to use and the game will chose which to use in any given situation (ex: if you get hit with a strike move = counter else if hit with a projectile = reflect) though we probably will not be able to freely set out a barrier like before it does seem like the start up of the move is EXTREMELY early (I'm talking frame 3-5 early) unlike the dreadful frame 11 counter and frame 8 reflect we had before.
however as a draw back reflect doesn't linger near as long it used to and counter could potentially deal less damage (not like it mattered the thing couldn't kill anyways). Due to it being a parry (if it is) it can also be baited
=========================
Another thing I speculate is since custom moves appear to be scrapped, they could also do this for Palutena's other B specials. It was not specified weather Explosive flame was side B or neutral B with a hold button press Autoreticle and Explosive Flame could very well be mapped to neutral B while 2 other specials could be mapped to side B. Keep in mind that her main appeal was having many types of special moves she could very well have 2 neutral B, 2 side B, 2 down B, and 2 up B, each move depending if you hold the button or light tap it bar down b (if it's a parry like I think it is)
=========================
As for anything else regarding normal or specials we do not know. There was a clip of her using f-smash which is still the same and another clip of her using fair (also the same). I should mention in the linked vid her dash attack animation seems to have changed as it hits before her shield goes up, but that could be because the game is unfinished. I fear if it's accurate to the current animation dash attack will not me invincible in the early frames but only the late frames instead which is pretty bad , but we'll have to wait and see
