It started out that there was not enough stuff there, and my point is that it is already full of stuff. For anything new to come in you would need to take out the old, giving no more stuff just new stuff.
Previously the area did not even have T2. But now I don't see a problem with the distance you would need to walk. If you enter T2, when you exit it is already half way down the street.
On the other side of the street, the only thing that would fit is the same as what is there. A show is still too big, think of the T2 as basically a show building and ET as a ride building.
Eventually they should change up that area, but now is not the time. There are many other areas of the park which need more attention now. Give T2 some more time there
