Isaac chances:
19.45%
I wasn't confident about Isaac's chances when we first rated him, and I'm still not confident about his chances today. The series for sure has a strong following especially considering both the original Golden Sun and Lost Age broke the 1 million sales mark, but I'm not sure whether the series has an influence comparable to most series represented in Smash, even the more "niche" ones like Pikmin, Mother or Xenoblade, and I don't have much faith in Nintendo considering it worthy of being one of their flagship series. The fact the series didn't get playable representation in Brawl when it was the closest to its peak at the release of a new Smash game and instead got an unlockable Assist Trophy is telling a lot imo.
The Smash Ballot definitely helps him though, considering his popularity as a Smash DLC pick is considerably above average, especially in Europe from what I've seen, though Japan seems to care a little less about him than the rest of the world from what I've understood (they still care about him, at least much more than Little Mac prior to his reveal, just not exactly as much as the rest of the world). The Virtual Console releases on Wii U also help him to get more exposure, so I suppose it's something.
Overall I don't expect Isaac, though I wouldn't be too surprised to be proven wrong. For my standards a chances score close to 20% is good for someone I wouldn't bet on.
Isaac want:
72%
I don't really expect Isaac, but that wouldn't mean I wouldn't want him. I remember I bandwagoned him prior to the ESRB leak because of "GBA rep" and "MUH MOVESET POTENTIAL", and I even bought the first Golden Sun on the GBA (didn't have a Wii U yet, so no GS virtual console for me at the time), but ever since I've changed my roster philosophy and I came to think that "GBA rep" is not really a good primary reason and I've accepted that just because a character has an overly massive arsenal filled with a huge number of different attacks that can easily be ported from the source material doesn't mean they need to be in Smash.
Did those philosophy changes completely killed my want for Isaac? Actually, no, I think Golden Sun is popular enough to warrant a playable character in Smash and it'd be sad to see a big fanbase of a two million seller series ignored in Smash. His moveset possibilities still manage to catch my interest, and overall I still want him to a certain degree. I would be happy to see him making it in, especially with a cool Venus Lighthouse stage with a big central platform, two elevators at each side which can act as additional platforms when they appear, and some occasional gravity changes.

Iwata tribute chances and want: abstain
I have no idea of how likely this is, and I don't care much whether it happens or not. I suppose a "Thank you Satoru Iwata" mention in the credits would be nice, but I'm not sure whether a trophy would feel right.

Final SSB4 DLCs predictions:
I'd consider Wolf as a lock, but besides that, not sure how to feel about this. Other DLCs I feel will be too hard to predict, and while I enjoy rating each character's individual chances, I don't feel like predicting the final DLC roster. My bet is on four currently unrevealed DLC characters, but whoever it is remains to be seen. Though I'd be disappointed if King K. Rool doesn't make it in.
SSB5 predictions:
I don't feel like speculating about SSB5. I don't know whether it will release, how Nintendo will evolve during this time, who will be the new director, and too much other unknown things, especially considering the fact the possibility of DLCs make cut speculation pretty much irrelevant (like, "[insert character here] won't be muh relevant anymore" "but they'll come back as DLC anyway"). The only thing I'd say is that Inkling is a lock if the next system is powerful enough to support a paint mechanic.

Tiki prediction:
6.30%
I swear I'll be furious if we actually get a "muh relevant" Tiki over King K. Rool... oh wait wrong Tiki? Okay then... wait what that Tiki is YET ANOTHER FIRE EMBLEM CHARACTER?!! Okay I'm done
Moonstruck Blossom prediction:
2.35%
We've already gotten a DLC Kirby stage without this music, so unless we get another... it's not happening.
