As if many people actually do that write movies. Unless you're in any way suggesting EU writers have a place at this table.
Of course not. But Micheal Arndt obviously knows how to write Star Wars and is passionate about it. And Lawrence Kasdan has already been involved in the franchise. What's important as well as skill is passion and know how - I mean your typical guy isn't going to know how much hate will come about from doing something such as bringing back Vader. Like I said, its a delicate universe, you need to know about it in order to navigate it.
