Looks like we're getting a new movie on 12/23, and a new OVA around the same time frame. Both are, unsurprisingly, Zero-centric. (Maybe he can have more of a personality nao, plz?) More info (in Japanese) here. OVA looks like it will have Manatsu Ryuu (Ootori Gen/Ultraman Leo), Igarashi Shunji (YAY!) and Hirata Misato (YAY!) Thus is the planning session at Tsuburaya that Manatsu Ryuu attended explained.
I make no sense and am about to fall unconscious. Sleep now.
