Isaac
Chances: F (0%)
Isaac had two chances to make it into the roster, Brawl and Smash 3DS & Wii U. Brawl because that was when he was at the apex of his popularity alongside Golden Sun. Smash 3DS and Wii U because he faced much less competition from highly popular characters although in hindsight we underestimated the potential series that could get in. With both opportunities, he failed to get in and not only that, didn't even get to keep his AT when Saki of all characters did. If that wasn't a bad outcome for him, I don't know what it could be.
Now his franchise is dead. Camelot, once a premiere RPG company, has been reduced to making Mario Tennis and Golf games to keep the lights on since they sell a lot more. If the franchise was going to come back, it would have been on the 3DS and it didn't happen. Predictably, Camelot's first game on the Switch is well, Mario Tennis Aces. That shows they do not have the money to make a HD Golden Sun because the cost outweighs the benefits and I don't see Camelot embracing a download-only route.
People will cite popularity and fan demand as a reason to keep hoping, that maybe he did well enough to warrant a slot on that merit, but what they don't realize is that Isaac is no longer at his peak. His Japanese fan base collapsed after he didn't make it in Brawl and even his Western fan base is withering away as the years go by without a new game. In five, ten, twenty years, how many fans will still be clamoring for his inclusion? People also overestimate the influence that the Smash Ballot will have on the game. We'll get one runner-up for sure, but certainly no more than two. Since one of these are likely taken up by the Inklings, how is Isaac supposed to compete with someone like King K. Rool if we get a second slot? There's no way we're getting anymore. In fact, we'll be lucky to get even that second slot so he's shut out.
Like Ridley, he will never make it in any Smash game. It's past time to move on.
Want: C (50%)
I don't care either way as I've never played a game by him. But I'm sure Psynergy can be interesting and except for the Miis, Sakurai has done a great job with unique move sets. If nothing else, like with Ridley, I also sympathize with the fans.
Bandana Dee prediction: 42.86%
People are going to rate him higher after Kirby Star Allies.
