Obviously it's pure speculation at this point, but who wants to make some predictions? New composer to SW, or proven talent? Conventional romantic orchestral style, or some bold new direction? (Please, not Kenny Loggins!)
I eould actually love it if Chris Huelsbeck was involved in the soundtrack in some capacity. I almost can't imagine a Rogue Squadron anything without him. But if not him, why not give any of the other Star Ears video game heavyweights a shot? Top of my list would be Mark Griskey or Clint Bajakian.
I'd like to hear the RS score expand on RotJ's "Into the Trap" theme; to me, that's the theme music of the rebel starfighter pilots.
