Hm. I dunno man. Sakurai is stubborn and I think the roster was set in stone before production even took place. I really don't think they'd swap him out for Lucina on a whim just because he was a little hard to programme or whatever (Why would that be anyway?). Especially in the short amount of time between the second Gematsu leak and the Lucina trailer.

Good thinking though.
