That's true.
You know, if Sora does get in, would Disney and/or Squeenix make sure that his amiibo is easy to obtain? (And I hope that, PS4 aside, Sora would have his KH3 duds because dat plaid, man)
EDIT: Been thinking; if non-Nintendo debut consoles aren't an issue, then one of my ideal "fanservice characters" would be Lara Croft.
She's a pretty notable gaming icon (especially where the jump from 2D to 3D is concerned, I think), is already highly physically-active and so has a lot of potential moves, and has a boatload of workable alt outfits. On a personal note, Tomb Raider was one of the first major VG series I was aware of (the other being Sonic).
