To bring the topic back to smash, I wanna point out something I realized that I told Mael, about. Out of all of the newcomers, not a single one is power oriented. The current newcomers follow these categories...
Villiger: Ranged, Set-Up, Oddball, Trap, Keep-Away.
Megaman: Ranged, Zoner, Guy with Guns, Keep-Away.
Wii Fit Trainer: Speed, Rushdown, Oddball, High Risk/High Reward.
Rosalina: Ranged, Gimmick, Zoner, Puppet.
Lil' Mac: Speed, Rushdown, Combo, High Risk/High Reward.
Greninja: Speed, Hit and Run, Mix Up, Teleporter, the "Ninja".
Characters whom I think have a good chance would fall under the following archetypes.
Palutena: Range, zoner.
Chrom: all rounded, combo, guy with sword.
Shulk: power, guy with sword, "charge" character.
Isaac: Ranged, zoner, guy with sword.
PAC-man: all rounded, oddball
Mii: all rounded, "jack of all trades", odd ball
Dillon: Power, tank, charge character.
K. Rool: power, heavy weight, grappler, oddball.
Takamaru: speed, guy with sword.
Rhythm heaven Chorus men: zoner, combo, gimmick, oddball
Rhythm heaven samurai: speed, combo, gimmick
Rhythm heaven wrestler: power, grappler, gimmick, oddball
Oh ya, did I mention the rumor floating around about there being a potential rhythm heaven character? The rumor strongly hints at the chorus men, but I personally think that the samurai and wrestler would be the best fits. I personally would like to see the wrestler for the following reasons.
1. He would be a power character, we need more big power oriented characters.
2. He has personality, and I can see sakurai coming up with something creative for him, he would be like a mix between DK, wii fit, and captain falcon.
3. Luchadors amuse me, the chorus men would be cool, but they are really random, the samurai also has no personality besides the fact that he goes HA YA! which is link's job
