WOW! Obi-Wan's Red R4 Unit rules! And with more screen time in the series than any specific droid other than R2 and C-3PO, I think he's definitely deserving of his own figure--and SOON! Bring it on, Hasbro!
[Note: Yeah, he looks suspiciously like the Red R2 from TPM, but you can never have too many Astromech Droids]
