I don't believe him.
So far he's said:
-Jajamaru is in Brawl (he's a very old NES char, I don't feel like doing the research for you--just know that his game was recently released for the Virtual Console)
-There is a ranking system--it has to do with that "submit your info" option Sakurai wrote about. You can get a permanent trophy if you're #1.
-He says Ridley isn't in Brawl. At all. "The Metroid series only has two playable characters, Sylux and Samus, and Sylux is very similar to Samus." Sylux is from Metroid Prime: Hunters.
-Takamaru the samurai is an assist trophy.
-Captain Falcon is in Brawl. He goes on to say: "Captain Falcon is nearly the same as he was in Super Smash Brother's Melee, but is a bit slower. His Final Smash is "Final Stretch", a random fighter get's "Rival" over their head, and Captain Falcon's ship Blue Falcon,slams toward them (Usually KO'ing, and when it does KO, Captain Falcon crosses his arms and poses with cool fire around him).
"
-He confirms Lucario and says this: "Well, for those wondering about Lucario,
Lucario requires one to collect 100 trophies to unlock, to me one of the hardest characters to unlock.
His A moves are actually punch combos, every single one of them!
This might seem stale but his B moves make it work very nicely. His standard B move is a blue version of Mewtwo's dark ball, I think it is called Aura Blast or something. Smash+B is Vacuum Punch, which pulls the foe to Lucario. Up B, is Extremespeed, which is like Mewtwo's Teleport, but it is directional like Zelda's, and it causes damage. Down B is Counter, (Think Marth).
His Final Smash is 'Close Combat', he dashes at the opponent (Like Link's Final Smash), and than unleashes a blinding fury of punches, easily KO'ing the foe at 40%+. "
-Says this about Wolf, Ness and Knuckles: "Ness and Wolf are both in Brawl, to get them you must beat Classic with Lucas and Fox respectively.
Wolf O'Donnell is an interesting character actually, because he plays much differently from Fox (Unlike Falco in Super Smash Brothers: Melee) He has no Blaster, instead he uses a Rocket Launcher similar to Snake's, and his UP+B is a Jet Pack. If anything he plays like Snake!
Sonic pairs with Pit/ Mario/ Kirby depending on the choices you make in the Subspace Emissary. You unlock Knuckles actually, by beating c-lassic Mode with him on Hard.
Knuckles is one the better characters to be honest. He is basically overpowered. He is a very heavy character, yet he is also fast on his feet... and he has tons of strong punches. He can actually climb ledges, when you use his UP B, which is Echindna Glide, and can burrow underground with his DOWN B. His Final Smash is a powerful punch to the ground that literally KO's anyone it hits, damaging anyone one the ground with shockwaves. "
-"Capcom has no part of this game, so those asking for Pheonix Wright and Megaman are out of luck."
-"You can expect however, to see two of Square's characters, Cecil and Geno. If you need more detail, Cecil is a faster version of Ike, with a different Final Smash, and Geno is a blue Scarecrow from some obscure Mario game that attacks using stars and lazers."
