We already know a little bit about Bandai's plans, but now details have leaked out from NECA that there will be two figures - one 6 inches tall, one 12 inches. Where this gets confusing is that some sites are listing the "head-to-tail" length as if it were the height - Godzilla is twice as long in that department as he is tall.
Both figures will have over 25 points of articulation and a bendy tail. The larger one will have sound effects. Word right now is that they will not be shown to the public at Toy Fair, but revealed at a later date of WB and Legendary's choosing.
If you trust the glimpses we've seen so far, you can preorder now.
