Since Disney plans to put out a non-trilogy film every year, there's no reason in my mind not to have a Dark Forces movie. After all, putting out such a movie would be an incredible springboard for marketing a Dark Forces 1.5 game. What did Kyle do between the destruction of the Arc Hammer and the beginning of Jedi Knight? I'm guessing the Arc Hammer was destroyed sometime between ANH and TESB, and JK is supposed to start a year after RotJ. Having introduced a new generation to the world of Kyle Katarn, Disney could make a game to go along with the movie.
They could also make another movie, also taking place between Dark Forces and Jedi Knight, that targeted towards women. It would be a romance between Kyle and Jan. In that movie, we'd also get to meet Jan's girlfriends. Those characters would form the basis for a new TV show, called "Sex and..." wait, what's this? Wookieepedia says Kyle proposed to Jan several times between JK and JK2? But she said no every time, fearing that "each day together could be their last?" That makes absolutely no sense. In "Team America: World Police", Gary only has to promise Lisa that he "will never die". After doing this, she makes love to him.
Maybe the moral is that any EU tie-in will need some massive retconning in order to get rid of various absurdities. For example, who knew that Kyle, and not R2D2, stole they death star plans? Were they a different set of plans?
Maybe it would be better to go far back enough in time, so that nothing has been written to be contradicted. We could have a 10-year old Kyle played by a 10-year old Jake Lloyd type person, and have him race swoops and interact with another CGI mentally retarded blackface alien. Or how about a 10-year old Scarlacc. I would love to see a movie about the Scarlacc's childhood.
