OKAY, so i finally got the Quicktime version and am watching frame by frame. Meta Knight and Pit are doing rolls. They clearly exit the plain of the stage, which is exactly what Mewtwo, Zelda, Marth, etc. etc. did for their rolls. And it is possible to input the command for a roll quickly enough that the shield doesn't appear. So yeah, Meta Knight and Pit just have really fast rolls
I think we do actually see Pit's neutral A. He appears to do his Forward Smash without his second Smash when he first appears behind Meta Knight, then follows it with a very light horizontal slash from the other blade. So he DOES use that move in the trailer... His USmash is shown against Meta Knight on the Pokemon Stadium level, and the reach looks amazing. He floats up as he does the multi-hitting smash, making it like a better version of Link's from Melee that keeps the opponent in for all three hits. He then proceeds to do either his Fair or Nair (though something that's more likely his Fair was in the E3 trailer, where he slashes both blades apart in midair). After that, he does a three hit combo on Wario, which I'm not sure if it's a Ftilt or his Rapid A. Later on, he does a rapid spinning attack on the ground that would work much better as a Rapid A, so I'm not sure what it is. Who has a Ftilt that hits more than once? (interestingly, Meta Knight seems to ALSO have tilts that are multihits)
Zamus shows some clipping (ONOS! :O) Her fingers appear through the gun as she's messing with it, and her ponytail pops out her boob when she's doing her headstand kick XD Those are all her tilts, definitely. No crazy sparkle. Also, her gun does change appearance between whip and shooting mode, and it's in the shooting mode (according to the E3 trailer) while she's shown fighting... Hmm
Okay, Snake is rolling around Pit, definitely. So what the hell is he doing when he rolls into that crawl???? Also, the RPG is a RPG, not a rocket launcher. But what's weird is that when he uses it, and it definitely has to be a Smash because there's the sparkle and everything, he slides forwards towards Pit. How is that managed? Also, I can't tell if he TOO has a Two-step Smash, or if his tilt is multihit, or what... That knee followed by an overhead hammer swing is so weird I can't place what A attack it would be.
Okay, some other tidbits in the final few scenes:
--Zamus has a really high second jump. Crazy.
--Pikachu is doing WHAT? It looks like a Down Smash and Mario starts Tornadoing into him, but then Pikachu starts going schizo and I can't quite make it out if its a throw or what. Zamus falls into it, and both her and Mario go flying. Pit does his cutting Fair to Mario right at fade out.
--It seems the castle/Fire Emblem stage has fireballs that come crashing all over the place. Cool.
--Wario's mouth gets HUGE when he's hurt. Mario's Fsmash has a bigger hitbox.
--Yoshi's Island stage has little Fly Guys that buzz around the stage. You can just catch one as the screen fades.
--The platforms in this stage also change. The top platform has a different angle in different seasons, the ghost appears to move back and forth as he is closer to the main platform in one shot and far away in another, and it looks like there are giant spikes (?) lining the bottom corners of the stage, like those big "chalk" like rocks in the SNES game.
--Meta Knight has a Nair similar to Kirby's, but more akin to his jumping sword slash in Adventure/Superstar. Nice.
--Wario's second jump has him doing a cannonball
--I guess I should mention that Wario's jerky movements are present everywhere in this trailer, so it looks they're here to stay
--Link has a wider range overall, which he sorely needed (less emphasis on projectile spamming, y'dig?)
--Everybody's sword glows when they slash. Link's, Pit's, and Meta Knight's.
--wtf? Wario is either crawling backwards, or doing some flying *** attack where he runs backwards into the enemy. He follows it up with Ftilt punch.
--Meta Knight glides, and it does not seem to be prompted by an attack. It looks like he may end up not having a third jump if this is the case, or he will and would basically be "EVIL PEACH" XD He definitely can "hover" by gliding, though.
--OMG ZLOL SNAKE DROPS A GRENADE/MINE AND IT BLOWS UP WARIO. You can definitely see it frame by frame. He tosses it up and destroys the platform as Pit is just below it. We can see the grenade/mine fall down, but the explosion is missed amidst the rubble. Pit flies off in a fiery mess, but it didn't too powerful, because he recovers easily. Definitely there tho...
--Snake does a freaking MONKEY LEAP for his second jump, and his Dair is some sort of boot stomp
--Pikachu IS crawling on the Yoshi's Island stage in the winter
--Wario's standing animation
--MK's Rapid A, followed by Pit's. Pit is twirling the bow like a staff in one hand, then passing it to the next, FYI. Looks a lot like Donatello. Heh..
--Okay, this is an interesting scene... Zamus, Snake, Wario, MK all on the Halberd. MK does a falling attack, then recovers by teching and rolls over the edge. He then does his Dash A, a kick, and plasters Wario. Zamus starts by dashing and doing her Dash A, which is a flying kick, and hits Snake over the edge. She then jumps twice, and gets massive air, before doing a flying kick downwards. Not sure if this is a fastfall or an actual attack, BUT she does rear up before doing it, so I'd venture a guess that it's an attack. Now, Snake uses his grenade/explosive again, but we only see his hand swing up and the explosion nails Wario. Wario recovers with his second jump, and doesn't really do anything. Snake gets nailed by Zamus, then bounces back and does a meteor just over MK's head. So there's a lot of attacks doing on in this part of the video.
--Woah, wtf? It's the new Great Fox that Fox is fighting on, but the original is in the background too! It's in a fight with a bunch of Wolfen and Arwings.
--Fox always has his gun out during the fight. Cool.
--Wow does he have detail. He has a mine attached to his belt. Design, or something else...? His tail does end in actual "fur," and his jacket has all these zippers and stuffed pockets. It's pretty cool.
--Fox is doing his regular aerial attacks while the Great Fox enters the atmosphere...
--Looks like Fox is doing the shine, but can't be sure. That camera angle is just that; a weird camera angle. The stage itself is not rotating.
...anyways, any more comments/additions/whatever, feel free.
