I am going to stick with my guns on this one. I am not going to spend over 200 dollars (with shipping) on a toy that has these sorts of quality control issues.
A product outside of Japan with Macross designs and BW gets some sort of credit? Would it be worth it to them to put a stick in HG's eye?
Who knows, and no point in really discussing it, I suppose. It seems like they aren't talking.
Looks like its an addition. Instead of producing new toys with the extension, they simply added it to the kit. But, hard to say for sure until someone here actually gets one.
