Well, i'm not sure that is the starting roster, seems like they just used the E for All demo roster. If that was the roster, i'm sure he would have unblurred the names update, as he did with snapshots after "submit" was confirmed... and plus, it's very weird to have meta knight a starter, and no kirby, as you said.
and seeing the icon theory puts GandW in a pretty good place, unless he's just messing with us (the number theory, not the failed name theory)
