I have a 4 bedroom house with 2 very large living rooms. I could display four of these without my wife breaking a sweat.
No pics, no proof.
Sur they are prototypes, but if they decide they made two and it's not possible to go to production with it it's doesn't change the fact that it's a prototype. The 1/6 bat was a prototype and they decided to make it in 1/12.
The new pics still make me question if it is a true 1/6th. If its made, it would be hard to ship these five foot tall wings....... almost unlikely. As you said, "prototype" Bat and was downsized to 1/12. Hot Toys loves to throw out the prototype word.
"Prototype" '66 Batmobile.
