Could not agree more. That VotV thing was complete garbage. This release of new Ethereal NPC's is more than likely having to do with blizzards LONG talked about release of cross-server mailing of BoA's.
Edit: When you lose an item, have something restored you used to get an email about how "Your lost item was recovered from the void". It only makes sense that ethereals would be the ones to fish it out for you. I am curious as to what the Transmogrifier does, though.
