basically the pic of the day confims this by saying this
"Pic of the day. This time, you can challenge every fighter in All-Star Mode from the moment you turn on the game!! This is a survival battle with limited recovery items and no option to continue. However, this mode will be incomplete until you've unlocked every fighter... Until then, you can only play against characters that are already available. This is a picture of the bottom-screen menu, with a padlock indicating that the mode is still incomplete."
now here is the leak pic for the menu of Smash Run
the leaker still has the lock icon so that means he didn't unlock the full roster.
