Cant believe a lot of you are giving up hope already. Ridley's chance as a playable character is all but confirmed with the cloak and dagger Pyrosphere situation. I understand it's a bummer that we haven't seen Ridley yet, but E3 isn't over. Even if he doesn't show up tomorrow though, think about it... Ridley was not debunked. He did not appear as a boss. You most likely feel a bit depressed because a lot of other characters you weren't hoping for were confirmed. You feel left out I know, but it will pass. We will have our day too.
To the detractors, and those of you saying that Sakurai said he was a boss during the direct, you're wrong. He gave you a visual idea to which you drew your own conclusion. If he was indeed a boss, we would of seen it today; if not through Pyrosphere, than through a video or other explanation such as the developer discussion. Sakurai has a plan for Ridley; and it's not to make him Pyrosphere's hazard. That's the lava's job as is always the case in EVERY Metroid stage in Smash history (as much as I hate it). Ridley's a major 1st party character to a flagship series starved of reps. When someone is excited for Ridley's chance to be playable, don't be that guy that tries to find every little detail no matter how ridiculous in an attempt to crush someones hopes for a character just because you don't like the idea, or because it's popular opinion. That's douchebaggery 101. There's really no excuse not to include Ridley in this game, and almost no argument outside of the ambiguous direct statement. Anything else (like size arguments, etc.) is just your own personal theory, and are rules Sakurai does not play by.
As for the Sal leak, don't be so quick to give full "leak" credibility to easy educated guesses. Pac Man is Namco's #1 and a gaming icon that Sakurai would never pass up while teamed with Bamco. Mii is a Nintendo icon since the launch of the Wii and a obvious good choice for many reasons; especially the customizable aspect. Palutena? She is one of Sakurai's pride and joy characters from his creation, and a perfect addition for another Kid Icarus rep. Everyone knew she was getting in. Chrom is another one I would say is fairly obvious. I will say this though.. if Chorus men are confirmed, I'll be a believer. But until the REALLY outlandish one is guessed, I don't count this leak legit. That's even tougher than WFT to guess. At least with WFT, you can see the obvious sales figures of Wii Fit to make a safe guess. Also, I don't think Shulk has a real chance anymore to be honest, but we'll see.
Anyway guys, Ridley's chances live on to fight another day. Don't let the down and out emotions conquer your hope and knowledge of the facts.
