Also, some news from the people at E for All:
-Fox can triple short hop laser.
-Fox's lasers have less range.
-Fox has a Starwolf outfit.
-Airdodging is now based on momentum and can't be controlled (ex. if you jump up and right and airdodge, you will continue going up and right).
-After airdodging, there's about a 1 second delay before you can do anything.
-Bowser is much, much better. Apparently he seems to be top tier. His claw attack is supposedly really powerful.
-Bowser has a golden costume.
-Samus has a dark suit with a red visor (Fusion Suit costume).
-Samus can't missile cancel and bomb jumping is much tougher to do.
-Samus's charged B isn't as strong.
-If you die as Zero Suit, you stay Zero Suit. Only way to change back is with another Smash Ball.
-Sonic's costumes are just different recolors of blue with different color wristbands.
-Sonic's moves don't have much knockback and he isn't as good as expected. Hardest learning curve.
-Diddy Kong has a Dixie Kong outfit.
-Link has a Dark Link costume (same as black link from Melee but with darker skin and red eyes).
-Ike's Final Smash-Must be right next to the opponent for it to hit but it's an almost guaranteed one hit KO. Does a barrage of slashes (think Omnislash).
-Meta Knight's Final Smash-Same as Ike's but with only one slash.
-Mario's FSmash is really slow.
-Peach is heavier. Her down smash was nerfed (not as much range) but can still do amazing damage if crouch cancelled.
-You can catch the edge even if you face the wrong way.
-Overall, the game feels much slower than Melee. Everyone is more floaty. Not much lag on individual moves.
