- In Kid Icarus, Pit used a Protective Crystal that spun around him, blocking/reflecting attacks. He seems to use this to protect himself from a Peach Bomber at the beginning of the trailer, on Isle Delfino. I´m guessing B-down.
- Fox´s Landmaster moves much faster than one would think.
- Ike was seen planting his sword (Ragnell) on the ground and posing. Appears to be a taunt.
- Lucas creates a PSI move that looks like PK LOVE. Could be a taunt, as it doesn´t seem to travel in any direction as the camera pans upwards.
- It seems that taunts now change depending on who you´re close to. For example, Link and Zelda´s taunts were extremely well-coordinated. Likewise, when Mario and Sonic pose in the "Sonic in Brawl" video it looks synchronized; unless these are animated poses exclusively made for the video, then alternate taunts are confirmed, as we already saw Mario´s standard "growth" taunt in one of the screenshots for the Wi-Fi update.
- Fox´s Fox Illusion is seen.
- Peach dances at the very end of the trailer, producing musical notes, and Bowser dances awkwardly in front of her. This could be a new B-move that forces characters nearby to dance, a taunt with a special effect, or maybe a normal taunt and Bowser was made to move like that for effect in the movie.
- Wario´s taunt is seen, where he opens his mouth facing the screen and then closes it with his hands.
- Sonic uses the Spin Dash, surely a B-move. He seems to be able to move freely while Spin Dashing.
- Sonic also uses the Bumper as an apparent B-up move, quickly ricocheting straight up.
- Finally Sonic uses a straight-down kick move many times in the trailer. While it could be his down-air, it looks more like a B-down to me. I thought it was the Fire Somersault from Sonic Adventure 2 because of the fiery effects accompanying it in a screenshot, but that actually comes from Mario´s Fireball.
- Kyogre is confirmed as a Poké Ball Pokémon, swimming through the air and using Bubblebeam.
- Torchic is confirmed as a Poké Ball Pokémon, spontaneously combusting (Ember?).
That´s all the interesting stuff I saw.
