I've been wondering about the same thing, V! But to tell ya the truth I'm happy YAMATO made their toys in diff. scale, this way we, as collectors, would have a lot more option and/ or variety. Take for example my own collection. As of right now, 99% of my valks are in the 1/60 scale. I do have a 1/48 of the VF-1S HIKARU, but of course, I consider this particular valk my price possession and that my friend is the only reason why I bought it in that particular scale. And as for the perfect transformation, one of the reasons might be that there's a degree of difficulty involved in having to duplicate the perfect transformation onto a 1/60. It's either that or YAMATO just got lazy!
