It's really not that simple. 10 years ago, most of the fanbase was in the middle of their transition between having dispensable income and having low or new commitments. They were either getting out of college or starting their new career. And the majority didn't have their own family yet. Also, the idea of buying from the international market was pretty new and there was a hype about it. Between now and 10 years from now, the likelihood of the fanbase being big enough or maybe even the same size to support new ventures in Macross toys based on the original animation is slim to nil. If there are going to be any Macross toys that size, it'll most likely be based on a new series. The only way we'd get a regult in 1/60 (IMHO) will be if they rebooted the original series/DYRL or made a movie based on the original designs. The chances of that is also very unlikely. But simply re releasing old animation is not going to cut it.
Yamato may plan to release a mass produced toy based on the regult but I doubt it'll be in 1/60. If I were them or Bandai, I would make it 1/100 to go along with the Hi-Metal VF-1. The Toynami regult looks great displayed next to a 1/60 VF-1 in fighter... but they'd have to release it next to a toy that it can be scaled with. A 1/72 would make no sense since there arent any 1/72 VF-1 toy (unless you go way back to the 80s version).
