Plus, I'd hardly call Skull Kid having "little hope". In fact, at this point I'd say he has more hope than ever before for one reason—the Mii Costume. Take a look at how many characters were Mii Costumes in Smash 4 who become playable this time around—K Rool, Inklings, Chrom, and Isabelle off the top of my head, and Isabelle was an Assist Trophiy as well. A Mii Costume is pretty much "almost there" in terms of playability, and look at the Skull Kid costume! If you give the Mii darker skin it's pretty much perfect! Plus if Sakurai replacing trophies with Spirits is any indication, 3D models are the most difficult thing for creating a character, and in terms of Skull Kid, we already basically have that in playable form. Just give him the right moves and voice and you're done.
