I find it to be evidence, or at least helps her chances, due to the fact that they're picking a lot of characters to help market recent games. You're right; Toon Link could perfectly market the Wind Waker HD and Spirit Tracks by himself, but if the developers had the chance to create an easy to make character that would further help market those games, especially Wind Waker, I think they would jump on it. Someone might think to themselves, "Oh, I can play the game that these characters are from on this console?" It's not something that has to be done, but it definitely helps drive the point across.
That's fine. Many don't believe we'll get a sixth. At least you're not biased towards a Zelda newcomer. Between you and me, I find it fascinating how much people will claim their favorite character is the most likely to make it into Smash when there's nothing that character has going for them. I believe that there will be a sixth Zelda character because we only got a replacement in Brawl, and I believe Mewtwo is likely to return, bringing the Pokemon roster up to six. That also means I believe Mario will get a sixth, be it Paper Mario or someone else. I have high expectations, I know.
And you could easily be correct. It's just that I've really only heard Marth and Zelda getting slack since E3, and I'm just trying my best to put two and two together. I wasn't really all that happy when they removed transformations. I thought that gimmick brought an interesting way of playing. Made it difficult for your opponent to get accustomed to your play style when you switch characters half way through.
Ah, yeah. For me, I realize that they've always picked the one most popular Pokemon at the time when adding a new one to the roster ever since 64. That's just how they represent Pokemon, while marketing their most recent game, movie, or what have you. I think it works. It gets the Pokemon fans who are purchasing every latest installment interested in playing a Pokemon from that game in Smash.
I'm one to believe that since Rosalina has stuck around after Galaxy is the reason that she's in Smash. If she was only present in the Galaxy titles, and nothing else, I don't believe she would be on the roster. Like I said, a character has to be relevant enough to their franchise to be playable, and I think Rosalina has earned it. Especially after being playable in 3D World. Different way of thinking though.
I believe that she was cut due to time constraints, and nothing else. Even though she was a clone, she was going to be a transformation character as well. That in itself would have taken more time to create. I think if Brawl had four or five more months of development time, she would have been on the roster. I think that Sakurai would revisit the idea of adding her due to what I said before; she's more than capable of representing the Zelda franchise. Especially since Spirit Tracks, the Four Swords Anniversary Edition, and Wind Waker HD have all released since Brawl, further expanding her presence in the Zelda universe.
Then I guess we're back to square one. Haha. That's alright. We'll just see what happens soon enough. I've very much enjoyed discussing this subject with you. It's not often that a controversial character such as Toon Zelda can be talked about in a civilized manner like this.
