I've given up hope for a YF-19FP, VF-0, and it looks like the GBP is shaky at best. It looks like Yamato is giving up on Macross.
What a shame, the YF-19FP would definately make money. It is probably the second most popular valk after the VF-1. A well made YF-19FP seems like it would make more money than the Garland IMO.
Why not release the 1/100 VF-0S? Test the market. If it sells use your license and make more Mac 0 toys. It seems a waste of money, time, effort to get a license for Macross 0 and not use it.
I guess I'll never see a toy of the SV-51.
