Saw this on CyberGundam, a new trailer of "Gundam UC" Episode 2 "The Red Comet".

Not much variations as compared to the novel it seems. The debut of Sinanju and Full Frontal's sortie against Nahel Argama should be very awesome.
October 30th release (Japanese cinema), November 12th release (DVD & Blu-ray disc).
