If you watched the CryEngine 3 presentation, the urban environment feels like a city however it looks different. The game takes near 2020 I believe, and in the video they showed thats most likely going to be what it looks like. It looked pretty damn awesome to me. It's futuristic looking as well, so it could be intresting. I also bet your still going to go to the island as well, becuase Prophets still there. And besides, why would you go away from basically the mark of the 1st game, which in this case, IS the island?
