1) I can't see Yamato not planning for the RA when they made the initial 0S. Screen time or no, it looks bad a$$, and Yamato is very familiar with the success of add on part for their toys.
2)Ugh, no idea and my wallet is going into convulsions just considering it... Wasn't the CAD work supposed to reduce the cost of producing these?
3)... my layer tells me to to discuss this with the public.
4) So far I only have a VF-0A, as my screen name implies I have an affinity for the CF version of all valks, so if the RA were to actually be released I would likely get a VF-0S to go along with it (one of the newer ones with POM sholders)
5)Again, I think Yamato was aware of the sales potential for the RA when they designed the 0's, as others pointed out, there are some point on the bakpack that don't seem to have any reason for being there. But we probably won't know until an RA is announced.
