If Eisner hired him, its because Eisner is confident Rasulo will carry out Eisner's vision for the parks.
Since I haven't seen anything to indicate Eisner's vision for the parks has changed, I see no logical reason to be optimistic.
Perhaps if Rasulo at least understands what attracts people to the parks better than Pressler did, there could be some small improvements.
But again, unless Eisner either changes his spots, or is replaced, his philosophy will prevail.
