LA isn't making much of anything(SW, Indiana Jones, or any other IP) these days. EA has taken over main publishing duties of SW:TOR, and Microsoft will publish the SW Kinect game. So really the only game on LA's schedule is Lego Star Wars 3 and that will be out in March. So scheduling isn't the problem, it will be if LA thinks there will be a big enough base for an Indiana Jones current-gen, non-Lego game. They didn't seem to think so when they cancelled the one a couple of years back.
And LA has generally never gone after big name actors for their games. I remember Billy Dee Williams in Jedi Outcast, and I'm sure that Christopher Lee has done something sometime(he's in everything), outside of that no big voice actors( that I can remember).
