However, Disney has told us they plan on releasing a Star Wars Movie every couple of years or so. They are also releasing a tV show right now. I think Disney is disregarding EU stuff and downplaying PT because they want to be able to build Star Wars back up from its foundation, its foundation being the OT.
Disney does not want FFG to make ships from the EU or the PT because it is going to want them to make ships from their new movies and TV shows. I am sure the future stuff will be cool.
The fact that Disney has no plan to ever stop making Star War movies means that FFG can pretty much draw from the new Disney material for as long as they want.
This was talked quite a bit in the discussion for the new Star Wars book "A New Dawn" review thread. In that thread, it was discussed how the people in charge of Star Wars for Disney (who have creative freedom) are treating all new material as canon. They are trying to avoid nullifying anything that has been done in the EU as much as possible, but it is a potential...if it messes with some new scheme they will cook up. It's also possible that they can actually take the old EU and turn it into canon. So, I think most of the EU should be OK, but there is a possibility that something could get nullified.
