Which means maybe they had enough time to create new movesets.
People said Melee was rushed, and uh...I guess I'll believe them with regards to cloned characters' movesets. If they really wanted to bring back the same characters with different moves, they've probably had plenty of development time (probably since the very beginning) devoted to doing so. For Falco and Ganondorf!
Alright, I'll give you an example. Falco vs. Krystal, as the second Star Fox character in Brawl, and which one has a more likely chance of being in the game.
Now, since they wanted to represent the SF series since the very first game, including Fox was a must. However, this immediately presented a problem: Star Fox Adventures was released after SSB64, and even after Melee, and until it was released Fox had never done anything outside of fly his Arwing. So, for him, they had to create a moveset from scratch. Logically speaking, somebody who is a trained pilot in a futuristic version of the Air Force, and a mercenary, is likely to be at least somewhat trained in hand-to-hand and gun combat as well. Hence, Fox's moveset.
But now we come to Melee, and Falco. Falco faces the same problem that Fox faced before SFA: that within the parameters of his universe he doesn't do anything other than fly a ship. How do we know that Falco is also a martial artist? How do we know that he carries a blaster? We don't. For all we know, outside of his ship Falco could be a total p****.
But, since Fox was somewhat changed from his 64 incarnation, they simply decided to make Falco be a "classic Fox". Hence, a clone with some of Fox's original attributes, notably the old blaster.
And now we have Brawl. Fox and Falco are known to Smash players, and since SFA we have had another character, one who is simply bursting with potential as a Smash character: Krystal (I'll tell you why later). Falco is a clone, and it is highly unlikely, given what has been said and what we've seen on the Dojo, that clones will exist in Brawl. Falco, in order to not be a clone, would have to be given a new moveset (also, they wouldn't be able to give him either of Fox's old movesets and accompanying attributes because the Brawl Fox has been nerfed from his past incarnations, and if they included older, better versions of Fox in Falco then nobody would play Fox). This immediately presents a problem for the developers, because they have nothing to work with when it comes to Falco. Not only would they have to, once again, design a moveset from scratch (which is hard enough in itself), it would have to match the parameters of the SF universe and be fundamentally different from Fox's moveset.
So we have Falco, who has nothing, versus Krystal, who has the staff and magic from SFA, and psychic abilities (she displayed telepathy and clairvoyance in SF Command, and I think I read somewhere that she displayed telekinesis in SF Assault).
Now tell me: which character do you think the developers would have an easier time creating? The answer is obvious: Krystal.
Not only does the above information prove that she is more likely to be in Brawl than Falco, the fact that her moveset would be unique also increases her chances, because that's the trend with Brawl's characters. Like I already said, Brawl has more characters than Melee if you remove the clones. And if you keep the clones, Melee only has 4 more characters than Brawl. This shows that the developers are extremely committed to making sure that every character within Brawl's large roster offers a completely different experience, and such a notion clashes with the idea of clones.
Falco is gone. Deal with it.
Since you mentioned Ganondorf, though, I'll say a little something about him as well.
I think Ganondorf will come back as a unique character. There are plenty, plenty of things they can do to make Ganondorf a unique character (hell, the forms of Ganondorf from OoT, WW and TP all fight completely differently), and he's one of Nintendo's oldest and most popular characters. He didn't deserve the appearance he had in Melee; he deserves his own moveset, whatever that may be. Besides, it'd be awesome and sensible to include those two "trinities" from two of Nintendo's most popular franchises:
Mario = Mario, Peach, Bowser
Zelda = Link, Zelda, Ganon
The Hero, the Princess and the Evil Guy. It makes sense. Ganondorf has plenty going for him as far as an appearance in Brawl goes. Certainly more than all of the other Melee characters that haven't been confirmed yet.
