Wow, aren't any of you aware that Ridley would look fucking weird scaled down? It's not like Bowser where he's basically just a ball of legs- thus a lot easier to scale down then say … Ridley who's just s skinny yet big fuck that would have a weird hitbox. Hell even in the old smash blog they mentioned him being far too big.
Now that being said, if any metriod characters DO have a chance to get a roster spot, it might as well be him since nobody else is really prevalent in these games. Still, I wouldn't bet money on Ridley.
Anyway, my preditions for the time being.
*Layton (If I recall there was something about him being invited to the game awhile ago?)
*Paper Mario (A good representative for all the Mario RPGs. We have "Toon Link", so why not an alternate Mario? He's very different from the regular Mario in terms of moves AND brings something aesthetically new to the franchise)
*Toon Zelda/Tetra (I believe they were supposed to be in Brawl or something? With the Uniqueness of Tetra and the special powers or whatever that Zelda's getting in the cel-shaded handhelds I didn't play, she'd seem like a good fit to make the rosters between Mario and Zelda equal.)
*New character from Kid Icarrus:Uprising (Sakurai is a biased fuck when it comes to making things, His favorite character Meta-knight is literally the BEST character, with his buddy's character being second best, hmmmm. Anyway his interest in the Kid Icarrus franchise kind of make this likely, I'd predict either Medusa or the big guy with the sword, he seems kind of important)
*Zoroark (sigh I don't really like this Mary-Sue of a pokemon, but given how it's marketed it's pretty much designed to replace Lucario)
And that's it for now.
