Emily from Hasbro was already fielding questions about "What's Next" for this deluxe playset concept. And she gave a great answer - they want to look at locations that are connected to strong story moments that might be populated with multiple characters. The palace (Jabba's, Bib's or Boba's) fits that bill. And it sounds like the Cantina is a prime candidate, too. From a design standpoint, they were saying that the depth of the playset is a consideration that factored into the planning of the palace playset. They were cognizant of the depth of standard shelving and designed it accordingly.
If I were to bet on this range of playsets going forward? I would say the Cantina is in a prime position. It's so beloved by Star Wars fans, and it's transcended the fandom to become an iconic cinematic moment. And then it has turned up again in The Mandalorian twice. And given Obi-Wan's line to Luke on the streets of Tatooine that "This place can be a little rough", I get the distinct impression that it could come into play in the upcoming Obi-Wan Kenobi series.
Other scenes that fit that criteria? A Star Destroyer bridge - see every Imperial figure you own, Darth Vader and the bounty hunters to fill it out. Someone mentioned the throne room from the second Death Star.
I agree with Muftak about sections of the Death Star. That's one place where I think the $50 playset range can offer up a lot of different scenes, offer up an army builder figure, and have the playsets interact with one another.
-DETENTION BLOCK HALLWAY - make the POTF2 version look like trash and take this one, complete with a cell. Pack-in figure - Imperial Navy Trooper
-DEATH STAR CORRIDOR - Basic corridor with the light panels and a blast door. Pack-in figure - Imperial Stormtrooper
Those two seem like the no-brainers. Do they go with a location like the DS Overbridge? Or a gunners station? Those are a departure from the hallway concept that worked for the Tantive IV.
