Not sure if I've posted this here, but I have a theory on why Rosalina was not leaked.
The first leak stated that Animal Crossing Guy, Mega Man, Wii Fit Trainer, Little Mac, Mii, and Pac-man would be revealed at E3 2013.
The second leak was posted before the Smash Direct, a significant news source for Smash info.
Rosalina was revealed during the December Direct (was it December?) which occurred after E3 2013, and before the Smash Direct.
Rosalina was not leaked because she didn't need to be leaked.
I'm under the assumption the leaker is going off of outdated info for the first leak. I think that the original plan for E3, which was leaked by Sal's tipper, was going to be those 6 (Killager, Mega Man, Miss Fit, Mac, Mii, and Waka waka) were to be revealed at E3. I think Sal's tipper had the info for the other 5 characters (Palutena, Shulk, Chrom, Chorus Men, and X/Y Pokeman) before E3, but since none of those characters were to be revealed at E3, he didn't mention them. (Maybe he abides by some bizarre moral code or something) Rosalina was never planned to be revealed at E3. There was no significant news event or press conference or anything noteworthy pertaining to Smash Bros. between E3, and the Smash Direct. (which hadn't been announced yet) Nintendo Directs just release general Nintendo info, not specific to any one game, so posting a Smash specific leak before one of them just seems strange. December happens, Rosalina is confirmed, then Smash Direct happens. Tipper decides to leak info. He doesn't mention Rosalina not because he didn't know, but because he didn't have to. Nintendo confirmed her already. I get the feeling that if Rosalina was not revealed before the Smash Direct, she would be a part of leak 2. Think about it. Would you say "Oh yeah, I knew about her." or say an already confirmed newcomer would be in the game after her reveal? No. It makes you look less credible as a leak.
This is just what I think, feel free to prove me wrong, discuss, do whatever you want.
This is just a joke, but how about Great Tigers as Smash Run enemies?
He
can make copies of himself!
Yes.
