I have the RO Vader which I've modified into an ANH, so I do still need a shiny ESB/ROTJ Vader in my collection. But now I'm undecided whether it should be this or the new 1/4 Vader. I kinda feel like one 1/6 Vader is enough for me, but $580 is also a heckuva lot of money...
I think I might just have to wait to see the final production pics for this one first.
I bet hottoys must release 1/6 Rotj vader like they release 1/4 scale bobafett frist then release 1/6 boba
