Implying disney publishing can make good AAA decisions, I cant see NT doing a star wars game because it will kind of cost them the art direction piller of there games and has we know letting Taini go nuts is what they like to do. On the other hand a star wars game is the hit best seller they been so waiting.
Ninja Theory did the combat mechanics for the Lightsaber Sword-play in Disney Infinty 2.0 and 3.0 so getting them onside for a full on Star Wars title isn't completely unlikely. However, despite Force Unleashed being an epic series, it recieved a poor receiption, particually for number 2 - so it seems less likely Force Unleashed would be ressurected instead of a brand new Star Wars game developed my NT.
Plus, as far as costs for development go, since Star Wars already has an extensive accepted canon from the seven movies to date, Clone Wars and Rebels, there wouldn't be a massive demand for 'new' material, just new implementation. :/
A Star War's Game by NT would staggering if you ask me, particually if they throw in a bit of Platinum's MGRevengence Sword Mechanics too -- a Lightsaber that actually cuts stuff and removes limbs of droids, that would be epic!
