To be honest, Hollywood Studios is going through a huge identity crisis and needs sorting badly (not to the bad extent of Epcot) but it still needs a big sort out.
The park doesn't serve its purpose any more of being working studios. It opened as Disney-MGM Studios and was a proper all-singing, all-dancing film studio/production area. Then MGM up and left causing it to change to Disney's Hollywood Studios. But, production of TV shows and editing of films etc all closed down in the early/mid 00's and the park has been left with an identity crisis since. We could argue this about WDS in Paris but that's a completely different ball game and was never built with working-studios as its purpose and it too, will be having a refit to welcome Marvel and Star Wars.
The Sorcerer's Hat leaving is one of the best bits of news! That hat was hated by many Imagineers and Disney lovers because it covered up the fantastic façade of The Great Movie Ride...but rumour is, when the Chinese Theatre's new owners (Paramount and Warner Bros.) bought the theatre in 2000, they told Disney for every photographed picture/vista with the façade included in it would mean they would have to pay for royalties...stupid huh?
Anyway, this is the apparent reason why the Sorcerer Hat was drafted in and became the unfortunate icon of DHS. Since it's implementation, huge annoyance and back lash has been aired by fans and even some Imagineers. In '09 during a DHS celebration, the Imagineer Bob Weiss commented on a photo of Chinese Theatre and said: “And this is my favourite view of the Chinese Theater. You can’t get this view any more. You may be aware of that. But I hope that we will get this view again sometime soon.” and what followed? Huge applause and cheers from the audience.
So, that's a good thing. The hat will go and I suppose the temporary icon will either be ToT or the original icon which was the Earful Tower. The Chinese Theatre will once again play host to a phenomenal centre piece down Hollywood Blv for the time being before, it too, is likely to close once Disney Weddings/Events have finished all of their bookings into 2015/16.
The problem is, DHS has issues with so many crowd flow problems, design flaws and the fact "Hollywood" isn't its direction/feel any more. Backlot Studio Tour even in it's watered down state (since the introduction of the stunt show) was still great fun but took up so much space and lost it's purpose slightly. The closure of the Backlot Tour, American Idol Experience and the American Film Institute Showcase points towards a big and exciting change for the park. Disney Hollywood Studios will be renamed and we'll get a (much cheaper) California Adventure-style refit. Cars Land will not be joining DHS in the way it is at DCA but elements will come over, along with the renaming and refurbing of park areas and also the introduction of more Pixar themes and Star Wars too. Marvel will not be joining any time soon either as Universal still holds the the rights to that over in East America (like for an age) and in Japan (until 2020) and the rights are ridiculous (and I won't bore you with them by going into detail over all that).
The thing is, I think DHS is definitely in need of help. The park is tired, cut up and confused.
Problem? Team Disney Orlando and Burbank just don't want to give WDW the love it deserves which WDI have been yearning for and why are they tightening the purse strings? Well, My MagicBands was a multi-million pound fail which has seen cuts, issues and shelved plans in multiple parks (bar Shanghai as that's a separate budget and also funded project in parks backed by Oriental Land Co) because TDO didn't address the issues but just demanded more millions. Animal Kingdom will have the bare minimum done to it in order to turn it into an "all-day destination" and Epcot will be left for ages unless WDI can push and persuade TDO/Burbank into giving it some updates.
But I have gone on a tangent, in short, whilst the expansion won't be a huge one like DCA due to many factors, we we will get will be a decent enhancement for the failing Studios Park.
