Wouldn't it be nice to be able to purchase the game as a PDF file and re-download a free updated and correction version as often as necessary?
I don't post this to be critical at Fantasy Flight, as I don't know of any company that tried this apporach before. (Maybe Green Ronin?)
Green Ronin has done that pretty consistently, especially with their Mutants & Masterminds line, often letting folks buy the PDFs a few months in advance, which in turn lets Green Ronin get a bunch of extra sets of eyes to catch any typos or goofs that made it past the editing process, and then providing a free PDF update once an updated version is available as well as cutting down on the number of errors/issues when the book does go to print.
But sadly (at the risk of opening this can of worms yet again), with FFG not being able to sell PDFs due to the terms of their license with Star Wars, such an option isn't available.
I'm pretty sure that if FFG could sell PDFs of their Star Wars products, they'd do be doing so, as it greatly expands the customer base given how many folks enjoy being able to carry PDF versions of their RPG books on their tablets.
