I managed to score two low-vis VF-1As. The first I paid regular price for, the second a little bit more on evilBay. Before my case of 1/48 fever had manifested itself completely, I actually considered passing on this one. I have no idea why.
I don't think collector's would be too upset if there were a re-release, given that Yamato pulled a similar move with the 1/60 CF. Murphy's Law of Collecting states that as soon as you buy something limited at an inflated price, a general release is announced. I wouldn't hold my breath for another low-vis, but if they released an S or J model, I'd probably pick it up right away. Another A would probably be too much of the same thing unless they did a completely new scheme.
I must say though, that this is interesting. One half of Macross World is saying, "I'm sick of VF-1s." and the other half seems to be saying, "Give me more VF-1s whether they're pink, camouflaged, or mauve."
