I like 3PO pointing out that his arm his red, but no reasoning for his arm being red, or if it even mattered.
Me and Dmartinjr had a discussion on whether the sith is still around. I don't remember the sith being mentioned in any of the first three movies. After the prequels, I assumed it died off, and a new "evil" came to power (even though Palpetine is still around).
So is the sith still around or gone?
