Rick,
I had no idea about all these details either - I've learned about them just recently when started preparing my own Vader armor for 501st Legion.

(I'm still missing chestbox, belt with beltboxes and I want to repaint the mask and chest armor (something strange is happening with the gloss varnish, and I want it to be just perfect), but I'm quite close to the end (I hope to finish completing it this year).
As for Disney and SW licences - I believe that we have to wait through the transition time... We already have some nice Marvel figures (and they're Disney's as well...)
Unfortunately LucasArt didn't make it
