So, based on this site linked off the Toyark new page,https://animegami.co.uk/shop/godzilla/g ... lla-30-cm/
Below are some estimated US prices on these pieces.
Giant Godzilla - $79.99
30cm Godzilla - $34.99
Monster Matchups (4" Figures) - $16.99
Monster Packs - $22.99
Godzilla Electronic Role Play Mask - $34.99
Again, this is just estimated based on one retailer and ahead of official solicitation, so take it with a grain of salt, but I figure for those like me who may want to pick up a lot of this stuff, it's good to start planning a budget and this is helpful and I think fairly realistic based on past toy costs.
