I am a huge fan of Star Wars RPGs.
The d6 SWRPG was the first game I actually ran, I've got most of the d6 SWRPG books, almost every book ever made for every d20 edition, and a number of non-RPG reference books.
That said, I"ve got next to zero interest in yet another SWRPG. Yet another predictable core book treading the same old turf, the same sourcebooks covering the same materials. Of the 4 published SWRPG's, I'd say d6 and Saga are my favorites, but I would probably run Saga because of supporting crunch for eras other than Rebellion and New Republic and a general like of d20 over d6 (although d6 isn't that bad).
I might have bought a GURPS Star Wars core book just for the fun of it even if I never played or ran it, but that's about it.
I don't need more miniatures, there, I said it. I've got huge amounts of starship and character minis from collecting the WotC minis over the years, dozens of Jedi and Sith, a dozen Stormtroopers and squads of all the various variant troopers, lots of, well, everything. I've got minis for everything Star Wars I could want to run from the Old Republic all the way through to Legacy Era.
As someone who has been playing and running Star Wars RPGs for 13 years now, I just wonder what could another game by another company offer that I don't already have. By the end of Saga Edition, I was buying some books just out of completionism.
