"Expansions are definitely something that we'll potentially look at in the future," Johanson said. "We don't have a timetable on it. We're open to it, but I think our major focus as a studio is making the living world concept as strong as possibly can for the players that we've got."
Asked if ArenaNet would instead consider developing a stand-alone third entry in the series, Johanson said gamers are more likely to see Guild Wars II grow and evolve.
"We want to be able to have teams that are literally developing new, innovative features that change the way that you play our game and grow that experience so it literally feels like you don't leave Guild Wars 2; Guild Wars 2 becomes Guild Wars 2.5 or Guild Wars 3, and it continues to grow," he said.
