That sounds like speculation as I haven't seen a source yet that mentions those.
Frankly, while the loss of jobs is sad, Lucasarts' shift is a good one. Which of the Star Wars games we know and love did they develop in-house? The Force Unleashed 1 was the closest they came to anything decent, and even it was a joke.
Lucasarts still exists, they're just a licensing entity. In my opinion they shouldn't have been staffed as a game dev company in the first place. 1313 was an example of that in its derivative, ostentatious nature. While I'm still not sure how I feel about EA owning exclusive rights I'm pretty confident that this is MUCH better than LA being left to development.
I just miss devs like Factor5 and Raven Software.
