I have one, so maybe I'll try it. It's been a while since I did some custom mojo. I agree with the points that Luke's only 'negatives' are the lack of ball jointed shoulders/elbows. Beyond that, he's great.
I think there will be select pieces that may sustain value in the future, but I can't see the point of trying to guess. The line has such a longevity now and items are so mass produced that folks thinking this is a down payment on the future will be disappointed.
Hopefully this pans out, because it will be one of the best waves ever. All of these figures with the exception maybe of R2 badly need resculpts. Throw in some gear boxes and extendable arms with R2, and we're golden.
The Hubble shows you much they don't care about education. The telescope has been and will be an invaluable tool to astronomers and scientists, but now it's too risky? Not nearly as risky as going to Mars.
