Twilight Town's an important and reoccurring original world part of the series, not from a movie, so it's just Hercules that's coming back from the Disney side of things(unless we learn of other possible returns).
Anyway, apparently, it was confirmed that the Pride Lands, along with Halloween Town, will not return for the third installment in an interview with Nomura.
http://www.designntrend.com/articles/58 ... ox-one.htmHowever, if the Pride Lands were to actually return, I'm willing to bet they'd probably skip over TLK2 and just use elements of The Lion Guard to help with marketing. KH isn't beyond that sort of stuff, as shown with the use of Chicken Little as a summon in KH2 to promote his film back in the day(primarily in Japan, since other regions got the game a bit later after the movie was released).
Also, KH also doesn't really do full on DTV sequels. It's true that the second installment kinda-sorta played out Agrabah similar to the second Aladdin feature, but the general concept is such a generic and predictable idea that it's less to do with actually adapting the film "The Return of Jafar" itself, and more like just bringing Jafar back and have him cause up a stir without actually following any movie's plot to the letter(although the whole Iago thing is a neat touch and a possible reference to his siding with the good guys in that film, which carried over to the TV series and KoT). They still didn't utilize any new significant characters from that movie or the storyline and stuff like that, though. It was all really just toying with the same idea of reusing Jafar as the antagonist.
Additionally, Square-Enix and Disney usually prefer to have more major features be represented as worlds. Sometimes they'd add an unexpected addition or two, but even then it's generally to bring something fresh and new to the table. Given this is the final installment of the Dark Seeker Saga, it's doubtful that they'd waste a world on a mere DTV sequel. The Lion Guard would at least be something to push and market if they reaaaally wanted to have an excuse to go back to TLK, but even the addition of that might be a stretch given the significance of this particular installment. And if the chances of that are iffy, then an old film that was part of a line of "cheapquels" John Lasseter himself put a stop to(because he felt they undermined the original features) isn't going to have a much better chance of making it in.
