Astro Tomorrow Kings by 3A Toys?

And while I have no doubt that these Tomorrow King headsculpts (posted on the threeA Toys-production blog) with the uniquely-shaped hair resembles that of the anime character Astro Boy (above-left artwork by Ashley Wood) - the question would be: **What Are They For?** = (1) Just mucking about with sculpts for shittes'n'giggles? (2) An upcoming super-secret release? Official or homage?
