Unfortunately, some playtesters on this edition went ahead and released information (and possibly the documents). I agree that an open play-test is a terrific thing (examples: Pathfinder, D&D 5E, Pathfinder 2), and I hope that Catalyst goes that route for future books. One of the difficulties is that Shadowrun is a six-book game. Yes, you can play the game with the core rule book, but they now have a history (every since 1st Edition, in fact), where the game really hits the mark after they are able to put out Magic/Matrix/Cyber/Lifestyle/Rigger books that give the players depths to the characters they want to play. It makes it hard to do a playtest without playtesting all the books, since they build on each other. D&D and Pathfinder can get away with playtest on the base rules, since any rules that come after are simply adding on to the rule, not making them more complex and intricate.
