This is pure speculation on how they can use the available area to them.
This idea provides more space for Despicable Me to receive a better queue by replacing the current Rockit location. It has horrible capacity and an ugly queue. Would provide them the ability to spruce it up a bit.
Note: This doesn't consider the special events building as a potential area for use. You could theoretically build a new media/special effects complex where the Rockit helix near Hard Rock Cafe is (therefore easier to access without the need to have USF open) and then use it for coaster space.
