I would also suggest that if the biggest and most successful roleplaying game company in the industry finds the Star Wars license too expensive to be worthwhile, chances are that no other company would really be able to afford it.
Your vision of the "industry" is too small by half. And in the wider gaming industry - even a company like WotC is, in fact,
a small-time player.
You are assuming that a company like EA/BioWare has no interest in turning a pnp game and setting development into a marketing and breeding ground for their own
Star Wars: The Old Republic MMO game.
Fit into the overall product mix of a successful MMO, a pnp RPG -- ANY pnp RPG - is
chump change.
Such a game would serve as a breeding round for writers and the development of canon, setting, characters and RPG concepts and integration of settings and stories into their overall game development and marketing hype for their electronic game.
My point: initially, TSR saw electronic game licenses as a way to enhance their brand. That's ancient history now. The market has developed so strongly for electronic gaming, that the pnp side of the equation is now a mere adjunct to the collossus that electronic gaming has become.
I think such an arrangement,
with the needs of the electronic brand calling the shots would be a strong possiblity for the direction of Star Wars --
and yes, D&D, too -- in the future.
I say it's not a matter of IF, but a matter of WHEN.
