Mario shows us that the Veteran will make changes and old Specials could ne normal attacks. i think there are some possibiliys:
Bowser Claw (B-> Forward) could be a Normal Grab even in the Air and also an Attack.
Peachs Bomb (B-> Forward) could be her smash attack.
DKs Down+B could know be his Smash+A+Down.
Kirbys Hammer could be his A+Forward and his Aerial+Forward+A Attack.
Captain Falcon's Raptor Boost could be his Aerial+Forward+A Attack.
That would be great becauce all of this moves are bad.
