The writer also revealed that franchise creator George Lucas recruited him for the spin-off project last fall.
"George (Lucas) sort of brought me into this part of it, and he's stepping back from the company. He's sort of given his blessing to everybody, and he'll be there if you need him. I think everyone's interested to see where this can go. It's been some very different places over 30 years. I think with J.J. (Abrams), we'll get something entirely new."
