X-Plus posted on their RicBoy Twitter page a couple of pics of what look to be future releases, Godzilla '95 and Keizer Ghidorah. Also in one of the images is a Titanosaurus, all are unpainted prototypes the tag for Godzilla says 30cm but the Keizer Ghidorah one does not.
Update: more pics and some info, all figure are scheduled for March 2017 release, prices are Keizer Ghidorah 21,600 yen, Godzilla 24,840 yen, and Titanosaurus 15,012 yen. Based on those prices the Ric Godzilla '95 should have some extra feature (per John over at Kaiju Addicts there will be no light up gimmick but will have some difference from the regular version).
