I highly doubt that they would remove Ganondorf AND Capt Falcon. They may remove one (since they are clones), but I'd almost guarantee that they wouldn't remove both. I think its more plausible that Ganondorf will come with a new moveset (then him being removed altogether, that is). The only characters that I believe are confirmed as removals are Marth and Roy; they're being replaced by Ike.
Also, do you honestly think they'd tell us about ALL the newcomers and stages? I really wouldn't be too surprised to see Ridley in there as something of a surprise since fans have been clamoring for him since SSB and since his background might be cohesive with the Space Emissary storyline (of which little is known about) for obvious reason. You can also bet that the last third party character won't be confirmed until the Japan release date, but I bet it'll be something big
