I'm not wholly convinced yet that it's only going to be one character a month until the game releases. Maybe it'll be that way for this year but there's still so many people left that have a decent shot at coming back and being in the starting roster that one a month would be way too slow of a pace unless 1. the game isn't coming out until late next year or 2. they cut a ton of people. From the way I see it, Yoshi, a Fire Emblem rep, a Mother rep, another Pokemon rep, Wario, King Dedede, Zelda, Sheik, Diddy Kong, Ice Climbers, Peach, Metaknight, and ZSS are pretty much locks for the starting roster and this doesn't even include potential newcomers so at some point the dam will have to break.
