You've a long way to go, my friend. . . You're maybe around 20 - 25 % at best(?), assuming / not assuming side-quest content.
As far as Chrom is concerned, I'm actually a fan of, and therefore I'm all for his inclusion in SSBIV. As for him being revealed tomorrow, though. . . I'd rather him be a secret character, or at a later date.
Edit: As for whether or not I'm going to use Shulk, it's my intention to. I don't care so much for who is to be considered top tier, but as a competitive player, if Shulk is just plain bad, there isn't any way I'm going to have him as my front. K. Rool, Mewtwo and Sheik are other characters I'd imagine myself using / wanting to use prior to the games release. There's also something to be said (for myself, personally) about how the game and how a specific character feels. . . That's usually how I decide upon the the first few, if not first day of release.
