My biggest problem with 47 is Ridley, he has a ton going for him when you look at the following points
-His shadow proves he is about the size of bowser, Ridley would not be that small when Sakurai said himself that the only reason it might not work is his size
-He is shown to have playable character like animations that Bosses have NEVER been known to have in Smash Bros, And while others might not see it, That looks very much what second jump would look with Ridley, Look at that and then compare it to Meta Knights
-We have already seen items that grant the ability to float and Ridley could have a move that lets him float in a single place for a small bit of time
-Why would Sakurai tease an extremely popular character with no positive outcome, he never teases like this, when something bad happens, he doesn't like to draw attention to it as shown when he revealed Charizard, he didn't mention him at all during the direct when talking about removing transformations, but instead just revealed him with Greninja to avoid having to talk about removing Pkmn Trainer, Squirtle and Ivysaur.
-He has been shown to "deconfirm" a playable character before launch as shown with R.O.B.
Ridley has far too much going for him at this point, Sakurai is a smart bloke, doing a stunt like this would be a horrible idea no matter which way you look at it.
