If/when MoM comes along I can imagine similar character interactivity slated for SW:GE and of course wands will come into play.
When I was at the Leavesden studios tour in london I can remember being amazed by the scale and detail MoM set and thinking how well this would work in a themepark, even more so than DA.
These two points get me excited without even starting to imagine what kind of a ride system they could use, multi directional elevator ride is the obvious, but for me, MoM could easily work as a walk through interactive attraction.
