this is bad news. my worry with Disney taking over is that they would go way outside the box on some **** and dilute some of the aforementioned qualities that the original films brought to the franchise. They should stick to the main Star Wars canon and, as I said in the other Star Wars thread, would be good to be faithful to the story lines that some of the Star Wars authors developed.
Darth Vader is part of the force now. Leave him there and bring him back as one of those Force apparitions only.
