I heard a rumor of this on the reales of ep 3 and I thought it'd probably never be, but I was reading something this week and Lucas said its still a few years off, but it will happen. He kind of talked of making the last trilogy, how he'd want to, but how he didn't want too. From what lil I've heard 7-9 it is Luke and the rebuilt jedi order. These movies could still be made. Mark is probably at about the right age now.
