I'll do the same as Genus, but, well, my predictions will be more logical/cool. yeah.
my 18 characters are as follow:
Confirmed/Given1. Luigi - Nearest main star of nintendo series, slip up by nintendo rep. Plus, if Pit is in, Luigi is. It's just a given.
2. Ganondorf- There's no way kirby would have 3 reps when zelda would not.. Plus, again, Ganon's been accidentally slipped. But the main villain of the second biggest nintendo franchise is clearly in.
3. Krystal - Sakurai wants more females in. Sakurai wants original (staff wielding) chars in. Star fox is a decently big franchise. Plus, accidental slip up, again.
4.Captain Falcon - Fzero is another classic nintendo franchise. CF has been with Smash since the original twelve. He's just waiting on a confirmation.
5. Jigglypuff - Pokemon is again a big franchise. Original twelve, original characters. Jiggs is back.
EDIT: Oh, accidentally confirmed as well.
Very Likely6. Ridley - Metroid is a huge franchise. One rep (Samus And zamus are one rep but two characters, attack my logic!) is not enough for the flourishing games. Even in Japan, where metroid is significantly less popular, ridley is very, very well requested. He's original. He's a baddy. He's a flying, firebreathing, heavy char. His size isn't a big deal (see: bowser). He's just -in-. The same way Diddy and Dedede were before him.
7. Olimar - Amazingly original. The star of one of the most original new series since melee was developed. You can't deny how amazing fighting with pikmin would be. You also can't deny that this is a significant series to nintendo. Hello, Olimar! :D
8. Game and Watch - Ice Climbers are in. That's pretty much enough to sway me.
9. Marth- I was originally part of the NO MARTH club. But then I realized.. who will be fe rep two? Marth is hugely popular based on smash alone, but in significance in other games, he's got fairly little. I think he might be in.. but this isn't a guarantee.
10. Falco - I was also part of the no Falco fan club. But since Wolf is deconfirmed, I find a declonified falco likely. Sidekick to Fox, was popular in melee, etc.
Note here I still say no to sheik, but I'm almost swayed on that one as well. :( I hope sheik's out. She's insignificant to OOT and has a pointlessly cheap moveset. People want the moveset, not the char in brawl.
Still High Chances11. Bowser Jr - Villain of two of the new mario games, original paintbrush based moveset, and a totally awesome smile. I'm really debating replacing him with paper mario, but eh. :(
12. Cel-Shaded Link- It seems contradictory to put up cs link and not paper mario, but I think CS Link is a YL replacement. I don't see a reason not to put cs-link in, really. The clone argument is not valid since you don't know potential movesets. yeah.
13. Megaman - Originated on NES, millions of gba games, and a very cool projectile oriented moveset. I think he's almost certainly the last 3rd-party inclusion.
14. Lucario - If mewtwo gets in, that means we have 7 pokemon from the original RBY games. That makes the 3 newere series entirely unrepresented. I think Lucario would make a better badass than mewtwo would, he's from d/p, he's qell-requested, and he's wellmarketed. Hoorah.
15. Animal Crosser - Yeah. So the icon theory suggests that AC and the touch generation need representative characters. I don't believe the theory myself, but it seems likely that a franchise of the strength of animal corssing will get a rep, anyway. Fishing poles and bug nets for attacks. Oh, boy!
Will the final smash start raining and summon a coelacanth? We will only have to wait.. assuming acer gets in, that is.
Not Exactly "Likely", but still good choices16. Balloon Fighter - Maybe I'm biased. I -love- balloon fight. But you can't argue with the awesomeness of this character. He floats with balloons! He's nostalgia'd out (which sakurai wants). The real kicker, though, is he was planned for melee! That seems to me like a clear reason to believe he may be coming. Even further, today's update showed balloon fight is recognized, as the fish made it into "summit" stage. Even more, it almost seemed to hit that more of balloon fight was soon to come:
I feel like I’ve seen that fish before somewhere... Where could it have been?
Hinting at balloon fight. I love it!
17. Stafy -
Yeah. You've never heard of him. That's cool. He's a Japan only character, but popular anyway. Two main reasons make me suspect that he may be in brawl:
A.) He's japan only. Sakurai said that he would like some japan only characters in brawl. Stafy would be perfect for this. His game franchise looks very fun, and brawl would be a great way to introduce the U.S. to Stafy, ala fire emblem.
B.) He's unique. He may look like Kirby, but he's not. He depends on spinning his body. I can see many moves derived clearly from his games. Those games are also very popular in Japan. He's not a one game hit, either, he's starred in many. In terms of being iconic, I'm not sure a japanese character is better suited than stafy.
18. Isaac - I don't know much about golden sun, but I know it's a well liked game and that Isaac is wellliked as a character, so i'll arbitrarily include him.
That's it. Now to wait and marvel at how spot on my predictions are!
