I doubt it's coming, for one, because Civ 5 is 5 years old now, and most base games apart from I think II, had two expansion pack each. However. Civ 5 is suprisingly popular. Between 30-50k people continue to play at any given time, that is huge. In Steam statistics it's one of the top 10 or so games. (mayb enot number 1, but still) Civ 5, despite it's flaws is quite a good game, and, I remeber making a thread long time ago asking if people wanted Civ 6 and were ready to move on and I remember the answer being a very loud NO. So.. would you buy a thrid expansion pack if Firaxis surprised us with one? I still can think of things the game could improve upon (won't name them so this thread doesn't get moved to Ideas & Suggestions). I personally would probably cash out. Beyond Earth flopped and we know it, I don't think even Rising Tides can help. And I think Firaxis would profit from quite a bit if they polished the game.
