Have I ever mentioned how all y'all are newbs?
Sonic
Popularity: High, both generally and in fans wanting him in Smash. He was a very well-received inclusion.
Relevancy: Before, Sonic had appeared in some exclusive games on Nintendo, but he was included primarily because of his rivalry with Mario. Nowadays, Nintendo and Sega get along great, and Sonic is one of the 3rd party series that appears most often on Nintendo consoles. With more Mario & Sonic games and deals for exclusives, Sonic's connection to Nintendo is stronger than ever.
Design: We've seen it. It fits Sonic pretty well. Hopefully they improve it for next time, because he didn't have the best designed move set. I mean primarily as far as balance, but it would also be nice if he had a less... repetitive set of attacks. I'm not really sure what the options are for that, but I'd also be fine if they just made him better.
Roster and Competition: I don't see that Sonic has any direct competition. Sonic is the only Sega franchise that will be in Smash Bros, and Sonic is the lead.
Legal issues: Sega seemingly doesn't have a problem with Sonic appearing in Smash Bros again. And why would they? It's great promotion for their character, and to an audience that will own systems that have Sonic games and players who are likely to enjoy classic platforming action even if it's not "mature".
Sakurai factors: There's a lot more uncertainty here than some people are acknowledging. What has Sakurai said that strongly indicates he wants 3rd party characters to become series regulars? He's said a lot more about 3rd parties being special cases and so forth than he has about any of them being guaranteed spots. That might just be him keeping expectations low for other 3rd parties, or to make Sonic and/or Snake's return that much sweeter, but there's a chance he really means it. Mega Man making it in probably helps though, since while Mega Man certainly is one of the most deserving 3rd parties (and one of my favorite video game characters), I have to say that Sonic probably is the most fitting.
Sonic chances: 90%
There are a lot of good reasons to include Sonic, and only one good reason not to (namely, that he's 3rd party). Sakurai's thoughts about that one factor are largely unknown. While the positive factors are quite strong, we have to allow some uncertainty because of that. I would be surprised if Sonic didn't return, but not downright shocked.
Sonic want: 70%
To be honest, it's more about the idea of Sonic being in the game, as Mario's biggest rival.
But I'm not the greatest fan of his games. His "cool" persona strikes me as very 90s nowadays as well. There's no way I can give him as high of a score as characters like Mega Man or Ridley. That said, his games aren't bad (least, not all of them), and I should probably give some of them more of a shot. Maybe I'll give his new game a shot... probably not til next year though. I'm a busy man and this fall is already packed with games I wanna play.
Genesect prediction: 18%
I don't really know what to put here. Pokemon already has a lot of reps, and a lot of the veterans seem to be getting love in the new Pokemon game (new forms for Mewtwo and Lucario, new type for Jiggly). Zoroark seems more popular... But I've been underestimating lately, so...
