I voted yes because I certainly want to see new content for the game, and see the ideas the team had in mind and early production, before GW2, realized.
However, I have to agree with Ghost and Cosy. The ANet of today is nothing like the ANet that created this game, and hasn't been since shortly after Nightfall. Any attempt by the team to do anything with GW1 would turn into an unmitigated disaster.
Quite frankly, I would just rather see the game ported to an offline single player mode so that we can continue to enjoy it after the servers are shut down. But I don't see that happening either. At best, we can only hope a team of fans can pull together an emulator to keep the game alive and maybe see more content in the future.
