From their website:
Due to continued manufacturing and shipping delays caused by the current situation in China, Monsterpocalypse Series 5: Big In Japan has been delayed and will release this June. The exact release date will be announced as soon as that information is available.
The remaining Series 4 organized play support kits have been extended into June on www.privateerevents.com in order to prevent any lapse in Monsterpocalypse organized play.
