More back story, more improvements, but no going to Bangkok. It's almost like the developer read that old Confucius saying "Man who walk through turnstiles sideways going to Bangkok", and he's afraid to go there. Patience, patience, patience.
I think the dev wants the framework of the game to be fully ready before implementing Bangkok. Apparently his plans for Bangkok are to have a sort of "open world" with a wide range of activities, RPG elements (rolls and various stats), improved sex engine, ... And if he added Bangkok before all those mechanics are ready, that would mean having to rework the Bangkok section heavily with each feature added.
Going the way the dev chose to go with means that in theory, once Bangkok does roll out it will just be a matter of adding content for each update, which would mean he could easily have new builds outs rather quickly, some which advance the main story and others that add more side activities.
I think it's a reasonable decision that may reap rewards in the future, but I can't deny that I'm growing more and more tired of having each playthrough end in Dubaï.
