Well thats the point, blizz don't want to nullify all the player's progress. Thats why they don't do that.And it was mentioed here aleardy, if Gw2 will have stand-alone successor, that will successfully take away company's attention. Gw2 support and player base will be Decimated.Gw1 servers are kept online only for Hall of Monument's calculation at this point. Player base there is very critical. And honestly, Hall of Monuments rewards are not for everyone's taste. I don’t believe that’s the reason they haven’t made a sequel. Players moving on to the newer game is how things go. That’s the lifecycle of a series. Nothing lasts forever. Exactly this. GW3 would likely only come out once they reach the limitations of their current engine and/or content. Past that, it makes far more sense to keep building on to what they already have. The only other case I can think of would be if revenue from GW2 dropped significantly and they needed a way to push a new game, but it would have to be above and beyond GW2 to get people to buy in.
