Thanks for posting about this Brian, I'd pretty much given up expecting a new doc. It's been what, 7 weeks or so since the last one?
This one was worth the wait. It really does a nice job illustrating the character's presence in the whole saga. I think it's refreshing to see the real, golden 3P0 too, and makes me even more hopeful than ever of Ep3 feeling like "old" Star Wars.
