the one in Disneyland only has one figure (Lincoln) and the stage is alot smaller than the one at WDW. the exhibit at Disneyland was never a Hall of Presidents. when it closed it was a history of Walt Disney and then the tribute to Lincoln.
I haven't heard that they were going to do more than just running the original figure. seems like they should be able to do more since the AA equipment is more advanced than the original.
