RE: The official Super Smash Brawl thread/characters.
^Agreed.
The rest of the Diamond and Pearl Pokemon really haven't been around for enough time. I believe the same kinda thing occured with Melee, because I recall the Ruby/Sapphire Pokemon being released before (That's only what I can remember, though correct me if I'm wrong) and it didn't offer any of those Pokemon.
And Silver, the chances of a Yugioh monster appearing in this game are slim to none, and I speak for the majority of us when I say I wouldn't want to see a Yugioh monster in this game.
Lastly, I saw that someone posted something about Tails.
My belief is that 1) Sonic will definitely be in this game (because of his huge fanbase). This leads me to say 2) Since Sakurai only wants three third-party characters, I don't think he's going to want to use up that last slot on a character from the same game as another third-party.
And please, don't even mention the "What if they were like the Ice Climbers?!?!" idea. I'm not saying that won't happen (Although the chances are still REALLY low) it's just that I would personally despise that idea in general. Sonic doesn't need Tails for any reason.
