There has been 0 instances where Lucas has signed away to the rights and allowed another company to do whatever they want with star wars. You have not seen the contract so you cant claim what you have just done. If you think EA has the upperhand in the scenario then im not sure what your thinking. Lucas/Disney will ALWAYS have the rights to the material. And im sure you know that every piece of word in the dialogue written by the SWTOR writers must go through lucasfilm to be approved.
