As for any conspiracy theory involving Disney's purchase of LucasArt, there's nothing giving them credence. The basic approach Disney took is to only keep movie-related production control and then license everything else. Disney has no experience in producing card games, and they have it already licensed to FFG, so why should we be worrying? The videogame example is different, in that LucasArt was developing the games themselves and Disney decided they were not videogame developers, hence now they are licensing it instead (didn't Ubisoft or some other company get a license deal already by the way?)
While I agree with you. I have read many articles and the concensus is that Disney as the new owner is terminating some contracts based on a clause that has something to do with new ownership and not having made the original deal. I am not a lawyer and I am not saying they did it to FFG and I am not claiming any conspiracy. I have just been reading a lot about what Disney is doing with their new product to position it (in their minds) in the best way for the future. And that does not necessarily mean FFG is in trouble or safe.
And as you pointed out, Edge of the Empire and X-Wing has been having a bunch of activity lately.
