Perfect Effect has updated that they will be released in June. This will include PC-03 and PC-04 (Superion and Mensaur add ons.) Their aim is for a more “G1” look for Menasaur (I like the sword add-on!)
PC-01 and PC-02 include hands and feet. So between these two kits we will see a complete overhaul to Superion and Menasaur.
