Swamps are fine, but an entire game based in one? Sounds like a bit much. Besides, based on the background material available, it sounds like they would have to retcon parts of Black Marsh to reliably program it into the game (the "Underground Express" comes to mind) or for the game to not seem too "one-sided", if you will. Black Marsh isn't really colonized; the population is near exclusively argonian. Then there's the whole mess with their language (Jel).

There would just be too many retcons for me to hope for Black Marsh. There's nothing wrong with it, and that's exactly why I wouldn't want it to show up. Then again, TES:O might end up retconning that stuff anyways...
