I tried L-Cancelling with Link's dair repeatedly this morning. All seemed to recover at the same speed as doing a dair without trying to L-cancel. And if a long recovery time like that isn't l-cancelable... doubt anything else would be. So that appears out.
I reconfirmed momentum dodging. You either can't control the direction at all (aside from being going in the direction you want before you air dodge, lol), or it's very very minor. It doesn't give any type of push, so it'll go to your normal trajectory and then start going downwards. So wavedashing as we knew it is indeed gone.
After you air dodge, there's about a 1 second delay (of falling helplessly) before you can do anything. You can jump and even Up B after that, though. I don't recall 100%, but I'm pretty sure that you don't get your jump back if you already used it. I also don't recall testing specifically if you can double air dodge, but it seems likely as long as it doens't give you your jump back and it would also explain the delay after an Air dodge (that way if you're falling to the stage, you can't spam air dodge and be safe all the way down). - So those of you thinking you'll Air Dodge and then do an aerial combo right after as a counterattack (thinking that's how aerial combat would be improved - which I think would've been sweet)... sorry, but not gonna happen..
Crawling seems to be like walljumping was, in that not everyone has it. I did it with Pikachu but couldn't do it with Mario (bah, he could crawl some of his games) or Sonic (so my friend was wrong, I guess). I almost thought that was Pika's walk after I thought about it, but the Nintendo World Video on the Dojo shows Pika using his old walk (along with Mario, right before Wario shows up). So crawling = character specific. --- The input for Pika was just diagonal down.
Dashing dancing appears to be possible, but different. It took me a bit, but I kinda did it with Peach, Ike, and Fox. Fox looked the most like oldschool dash dancing, whereas when I did it with the other two it was taking me longer to turn around (think Zelda's dance dash...). I kept jumping out of Fox's... but it's not like I'm used to using the Classic Controller.
I didn't see an opening dash move for Fox (where it'd be most noticeable to me) when I tested, so foxtrotting looks to be gone.
We already knew this, but shorthop and fastfall are still there. Also, you can jump directly out of your shield (was shielding with Fox, and hit a jump button on Classic Controller and he jumped out of it).
As Zauron isn't going to have the time to keep this thread updated, I'll post a full report of what I've learned in the Impressions thread. Prolly 5 hours from now or so, as I don't want to start on it at work, but not be able to finish it.

Lastly, Dark Link looks friggin' awesome. If you think otherwise after seeing him, you need to have your eyes checked and/or may not have the ability to recognize sheer awesomeness (in which case the rest of us both pity and laugh at you). - Think Black Link from Melee. Now makes his skin dark brown (think... really severe tan). Now make his eyes glow red. And that's Dark Link in a nutshell.
