Disney needs more attractions in its third gate, period. Taking away GMR is so stupid. A couple of low capacity carnie rides in TSL and a couple of mid-capacity, going to be mindblowingly popular E-Tix in SW still leaves the park a mess with not nearly enough to do.
EDIT TO ADD: That also includes the MM ride. ... Even with all of the above, this park will be woefully short of things to do. Unless, you just want to gawk at details in the SWE. My guess is there's only so much of that OCD component before people want more attractions. And there is nothing major at all being planned yet when all of this is done. Plenty in blue sky and such.
