Who knows how Sakurai works this time. During Brawl I kinda expected the likes of Dedede and Pokemon Trainer to be unlockables but in the end they all winded up being starters with the exception of the third parties. So either he decided to be cool with revealing more unlockables or he still works in that way and only
and
will wind up as unlockables by the game's release.
Not to mention if he's cool with revealing all unlockables, then he sure is taking his sweet time revealing the rest of them. I kinda really only expect him to reveal Ice Climbers, (Lucas?) Wario and Meta Knight up until the game's Japanese release up to this point. (Maybe Ness, Captain Falcon and Snake too)
I don't know, but I guess I'll just stick with them being starters for now.
