What I'm curious about is how this sudden announcement is coming right after EVO 2k14. That and Nintendo, who's sponsoring EVO this year, apparently has an announcement planned after the Smash Melee finals.
I'm thinking the Monday announcement is primarily for people who don't know what EVO is. And plenty of people do not know what EVO is. For all we know, we could learn the newest character this Sunday. It would be silly otherwise to announce this Sunday that there's going to be a newcomer video on Monday.
Considering that, I don't think any of the Gematsu leak newcomers are appropriate reveals for a crowd like EVO. It can still happen though. Nintendo may just think they're being good to the fanbase by using EVO as a podium to announce a brand new Smash character.
...All the same, Ridley being revealed at EVO would turn the entire place upside-down. Shulk would be a distant 2nd, and I can't imagine Chrom exciting a crowd like EVO that much. And Chorus Men..... No.
....But I could be wrong. In that case, what in the world does Nintendo have planned this Sunday?
