Outmaneuver rulings:
2008-04-01: If a creature is attacking a planeswalker, assigning its damage as though it weren’t blocked means the damage is assigned to the planeswalker, not to the defending player.
2008-04-01: Creatures damage the defending player or planeswalker even if the blocking creatures are no longer there at that time.
