i personally think tails would be more interesting then knuckles. and im pretty sure that what bluydee said means that they wouldnt give more then one slot to the same character. i personally dont think they will use another kirby (even though there are 2 links).
I don't know. They had Mario and Dr. Mario too. Probably no yarn Kirby though.
Things I hope for in SSB4:
-NO TRIPPING, OR AT LEAST OPTIONAL !%!@$^!#@$
-Better stages. The ones in Brawl were okay but had a lot of annoying features...like at Sky Pillar it's always the same Pokemon that comes, or Hannenbow where you use an up+b to get back on, would make it, except the leaf moves up and so you fall.
-Change how fans work. It's stupid that some characters can give others 200+ damage with no way out.
-Remove/change final smashes. They currently are extremely unbalanced. Falco's is the most rigged in the game, easily able to kill multiple people twice, while Mario is lucky to do 20 damage with his.
-I want Megaman! Capcom would have to cooperate though, so I won't blame them if he's not there.
-Interactive terrain. I loved the pipes at the Secret Mushroom Kingdom in the first game, where they randomly moved you around the level, sometimes into the pit. More features like this would be very nice.
-Remove Jigglypuff already, jeez. She's a weak, slow kirby that kills herself using half her moves and shield.
-Make Ganondorf better. He's supposed to be the ultimate baddy in LoZ, not some old guy who moves at half a mile an hour and can't jump.
-Balance Pikachu's down+b. A wall of high impact lightning that starts 30 feet above him is OP and kills way too easily.
-Again with Falco, his reflector is OP. It trips opponents most of the time, knocks them back, reflects item from behind even if the reflector is currently out front, and activates instantly.
-Team healers need to go, or be changed. They're a stupid item. At the very least they should be self applicable by throwing downwards.
-Wario. How I hate him. Annoying, glitchy, runs like he only has 1 foot, stupid moves and horrible sounds for his moves. No more Wario, please!
-Assist trophies. WHO'S DUMB IDEA WAS IT TO MAKE A PUPPY BLOCK THE SCREEN, OR A MOLE THAT NEVER SHUTS UP IF SOME ONE HITS IT? The vampire guy is okay though. Tingle doesn't ever do anything really, aside from hammer spam, everyone trips all the time anyways.
-Poke balls. Seems to me like the pokemon this time around weren't very fun to get half the time. Most often it's either Torchic, Chikorita, or Wobbefett. Kyogre is OP.
I think that's all for now.
