All clones from melee are gone but
ike and marth
lucas and ness
mario and luigi
bowser and bowser jr
star fox and star wolf
i didn't see zero suit samus at all or is that the blue thing next to samus?
Okay, I'm going presume others have pointed out how incredibly obvious it should be that the roster in that video is not real, and focus instead on this aspect of your ignorance:
Ike and Marth are not even close to clones. Look in the Ike subforum - they have compilations of his moves learned from E for All - and learn just how different they are. He has a grand total of 2 standard moves that are somewhat similar to Marth, and one special move that is the same (Counter, a generic special any sword-wielder could have). He has more similarities to Link than to Marth.
There is no reason whatsoever that Bowser and Bowser Jr or Fox and Wolf would be clones. Bowser Jr is much smaller than his father, is not known to breath fire, and is known to use things like the paintbrush from Mario Sunshine or airships from Galaxy to aid him in battle - anyone with an average imagination could create a moveset for him that isn't even close to Bowser's. Fox and Wolf barely even look alike, and with all the different options for space-age technology out there the idea that they'd be clones is ridiculous. (And this is coming from someone who hates Wolf and mildly dislike Bowser Jr, mind you.)
And assuming Luigi and Ness would be clones is equally foolish. Luigi was partially decloned going into Melee, and will almost surely be completely decloned in Brawl given the intense negative reaction fans had to them in Melee. Ness is an even worse assumption, since his moves came from another character in his game, so it would be ridiculously easy to give him new ones that reflect the powers he actually had, thereby differentiating him from Lucas completely.
And you won't see a spot for Zero Suit Samus, since shes a transformation of Samus using her final smash. Sakurai told us when she was revealed that she wasn't "a pure character addition," just a transformation, so this really shouldn't be news.
