Wavedashing is gone, it seems. It's been replaced with a minijump designed to dispel your momentum rather than manipulating for a faster move speed. I guess people will have to find some other way to manipulate the physics of the game.
Moves now have diminishing returns, in an attempt to stop people from just spamming one move over and over (not that it's stopped that, from what I've seen of some of the videos).
A pivot grab has been added. Run one way, switch direction, and grab on to your opponent. It increases most people's grab range, though I wonder what it will do to people with grapple grabs.
The principles of the laser show up in Brawl. The more a beam bounces back and forth between reflectors, the more powerful it gets, until it is strong enough to break through one of the reflectors.
There's a couple more small changes up. It's nice to see the level of detail they're putting into this.
