User blog comment:Tepig921/All characters and stages for SSB3DS leaked? (UPDATE 25/8/14)/@comment-32390199-20140822201436

Your first note is missing something. The 3DS version has more stages than Brawl had, as confirmed by Sakurai in one of his potd. So the stage screenshot doesn't make sense.

Also the leaker did say that he hadn't unlocked everything.
