My thoughts and predictions would be to remove Panda and NBCUE and Stage 28 could become a new restaurant venue. Expand the current restrooms to become much larger and leave then where they are today. When you see an aerial photo, you can see the current gift shop/Panda/NBCUE/Transformers extended queue are in the way of street growth.
Of course, this could also become a new Studio Tour loading and unloading zone...but that is dreaming!
I highly doubt if we will see an attraction in this corner, but my validity has become shot with this topic in recent days! LOL
