Ordered two sets of YF-19 stickers on 2-1-07 got them on 2-5-07 and must say they look great.Now to wait for the "YF-19,fastpack,fold booster" set to come out.
From Graham's Interview with Yamato "The Heavy Arm Weapon is not planned at this time, due to lack of any official line-art."
I'm not sure if that's the same weapon but it may very well be.
One thing to keep in mind though and this is not meant to excuse Yamato's recent flubs.Takara is a much bigger company that has been in the transforming robot game for a lot longer.
Ok I've been out of the loop since right after the 1/48 Max-Milia VF-1j supers came out.But I remeber Yamato saying they had no plans for 1/48 2 seaters even then. Something about the nose going to be to long or some such.
