Let's get the easy one out of the way...
Ryu Hayabusa
His situation reminds me of Snake and Mega Man. All three of them are important to Nintendo's early console history (being big games on the NES) and vice versa. However, while Mega Man maintained a significant presence on Nintendo platforms throughout his history (having multiple games on all Nintendo handhelds*, and some presence on all Nintendo home consoles), Snake went to be a primarily Sony character. Ryu Hayabusa went on hiatus for a decade, and since his return he's been solidly multi-platform (and the Xbox and Playstation seem to be higher priority than Nintendo consoles).
Basically, he was Nintendo relevant, and now he's not really. The difference between him and Snake? Kojima being friends with Sakurai. Without that, there's no way Snake would've ever been put in. And likewise, without intervention from an interested party, I see no chance for Ryu. He also hasn't remained as iconic as Mega Man, Sonic or Pac-Man, IMO.
*Mega Man doesn't have multiple titles on the 3DS unless you count virtual console... but there hasn't been an original Mega Man title since it launched either.
Ryu chances: 0.1%
Ryu want: 5%
Meh.
Prof Layton
Well, I'd agree if he were first party then he'd be a shoo-in. That is, however, true for almost any high-selling 3rd party character. Bomberman, Simon Belmont, Ryu Hayabusa, a Tales rep, Rayman, Crash Bandicoot, Crono, an FF rep, a DQ rep, etc. all would be shoo-ins if they were Nintendo characters/series. But they're not.
I highly doubt we're getting more than four 3rd-party reps. And Pac-Man and Snake are the most likely candidates for those spots. Even if Snake is out, others like Bomberman could take his spot. I'd personally like to see Simon Belmont or Bomberman more than most any of the other 3rd parties. But none of them seem likely.
I will grant, however, that Layton has unusually strong ties to Nintendo for a 3rd-party character which really helps. And he has some move potential... But I just don't see anyone but Snake and Pac-Man as likely. I'll grant him... "possible".
Layton chances: 4%
Layon want: 45%
Mostly indifferent.
Predictions
Halcandra stage - 20%
I dunno anything about this. But it seems like Sakurai has stuck mostly to classic Kirby for his stages, not just going with the most recent games...
Mewtwo - 79%
Why the rerate already? Nothing has changed. I'm assuming this is people upset about his score falling, so I'm going to predict a slight rebound for him.

Sunshine Airport seems unlikely since we already have Pilotwings. Buuut I think most of the new courses could work. Except Bowser's Castle which doesn't need to be a Mario Kart stage. N64 Rainbow Road is also pretty great looking.Mario Kart 8 Stage Want: Abstain
My want would be entirely dependent upon which track they select, and I have no idea which one they would. If it does happen, fingers crossed for Sunshine Airport.
