My understanding is the original park concept that was presented and green lit was one large CityWalk in the middle accessible to all with shops, restaurants, and entertainment. The big draw would be a nightly lagoon show that this CityWalk 2.0 would partially wrap around. Each of the lands of the new "park" would have an open boarder concept that let guests walk in and pay for lands piece by piece or together. There were no turnstiles or traditional entrance, just walk in. They really wanted to swing for the fences and redefine what a theme park is and could be in the 21st century, so let your imaginations run wild there. Last I heard the concept was shelved for something more traditional either due to feasibility, testing, or budget.
IMHO the idea isn't terrible and could have worked but guests need a more traditional method of park entry and this tried to take too many leaps forward. Introducing a gate-less system at USF/IOA first would have been a better step towards this model.
