I bet this topic was brought up before, but I wasn't able to find anything specific.
So GW 2 would not have a monthly subscription, I get that part. But would the money that the developers get once per expansion be enough for them to keep developing new patches every few months, like in WoW type of MMO? Where will they be getting the money to work on new content, besides purchases of the game? Again, I apologize for the noobish question.
