I don't see a problem with not allowing DLC being the reason to cancel the game. Just put all the maps into the game when you release it.
I probably wouldn't buy it anyways. I like WW1/WW2 weapons and settings way more than modern weapons and settings.
Someone should make a WW1 game where you die instantly once you leave the trenches and you sit around in muddy trenches all day looking at your dead comrades.
