I'm sure it's wishful thinking. But, it seems like there is a potential story emerging here that could actually prove better themed than the original park's overall theme. I'm envisioning sort of a classic Hollywood Blvd. as the main entrance. With a sort of "current Hollywood/LA streets" connecting Hollywood Blvd. hub to the various lands as transition areas - namely being Echo Lake, Grand Avenue, Comissary Lane, Sunset Blvd. and whatever becomes of Pixar Place. In a way, that actually could really work. It allows for "disconnected" attractions to land on the connecting streets (50s Prime Time, ToT, OMD, Sci Fi, etc.) while having the grand areas of SWGE, TSL whatever Animation Court becomes (or really could stay with some additional themeing), etc.
No clue if that's the overall plan, but a thought that came to mind.
