They managed to land a hard hit on Obito, but I too am not yet sure he's actually defeated.

Kakashi scored an even "more fatal" hit on Obito before and he survived long enough to become the Jubi Jinjuuriki, which fixed the wound.

If the Jubi could fix that wound before, this one might be healed too.
