Isaac
Likehood - 55%
Isaac strikes me as a rather middle-of-the-road character, one without an excess of credentials to differentiate himself from the pack of protagonists vying for the same niche in the game. He has popularity to his name, but is hardly a standout fan favorite, clocking in at roughly the bottom of the West's Top 10 most wanted. That said, his psynergy certainly gives him a wealth of abilities to bring to the table, which I'm hoping results in him being prioritized over Shulk, who most view as his most immediate competition. One item that gives me a moderate degree of confidence in Isaac's favor, aside from that he's been an AT and the star of a series (rather than a single game), is that the series he represents is handheld. He'd be an ideal candidate to accompany the focus handheld titles are receiving on the 3DS. I dislike the notion of characters 'missing their chance' for a Smash game, but I think if Isaac were to be absent from this game, it would be a steep, steep uphill battle for him to get into any future title.
Want - 40%
I'm not a fan of sword-based movesets, though if Isaac were to get a gimping playstyle with his 'Move' spell among others, I would want him a whole lot more. Otherwise, his series has great stage and music potential, so I'd hope for him for those reasons as well.
K. Rool Prediction - 58.5%
Too many 13-year-old relevant gits on GameFAQs for him to score much higher, sadly.
