Firstly, thank god they are considering changing it. Urban Wasteland is an incredibly generic name, and since it was revealed in EGM in March, has been considered a place-holder until they chose a real name for it. So it looks like they are finally doing that assuming Urban Wasteland doesn't pull out a victory in the poll.
I don't want to sway your voting...but please pick "Aftermath". Its by far the best sounding name of the bunch, while doing a good job at describing the map, and right now the battle of votes is between Aftermath and Urban Wasteland. So if we have any hope of changing the horrible "Urban Wasteland" name, its by voting for "Aftermath".
