They're for Coruscant, or at least they may be for Coruscant. I don't want to put anything on record yet, but I've been in contact with various individuals and we've discussed ideas for the planet and how to integrate it into the game. I didn't exactly plan it that way, but I was asked and then Har was already working on Coruscant areas anyway, so things just fell into place. But we're waiting on the completion of the area models to do anything more than planning, and that may still take some time. Well, they don't have to be completed exactly, but there is little practical work that can be done with the design before the areas are serviceable - enough to wander around in them, decide which areas the player will have to visit for the main quest, which will be optional side areas to explore, what to fill them with. There's only so much that can be done on paper. So, we've been waiting on the areas to be modeled, which understandably takes a very long time because it's a lot of work. Some adjustments will likely be required as well, even additional areas, as they've been primarily designed for Har's other project. But we've also been in communication throughout the process, so there is a lot of overlap too.
Anyway, I don't want to get anybody's hopes up because even if the models were done today, any real progress would still be in the distant future. But it's not nothing that's being done either.
