dave - I think that bit above the wing is there because of the way yamato designed the legs. in the line art, the leg sits underneath the wing. In the toy, the wing root sits along the leg...
maybe this is the reason for the leg bend, to accomodate the wing root?
in any event, unless it ends up the leg armor has the missile launcher bit, I think I'm going to pass on the FP. There's not enough there that I can justify the price and Graham's hints of wallet shock has me turned off.
IMO, they should release the FPs WITH the yf-19 (specially for what they're asking) and sell the fold booster as a cheap add after the YF-21 comes out (which I am assuming it does).
