X-Plus has teased on there website for December releases of King Ghidorah and a Godzilla/Mothra two pack no details were given but Ghidorah was shown at Wonderfest (pic below) and it appears to be Godzilla '64 and Mothra '61 as the two pack. 

All figures are 25cm versions although Ghidorah stands quite tall compared to the others, more info as we get it.
