The studio is still wholly committed to the game
Do you still play Guild Wars 2? I do, and ArenaNet is listening to the folks who want more updates. Specifically, it looks like they're going to target updates every two weeks instead of a three week timeline.
Speaking to Gamerzines, ArenaNet's Mike Zadorojny noted that even though they're currently updating the game in three week increments, they're "pushing to two weeks." He went on to explain that "it's a marathon, not a sprint, and we've been getting better with each of our releases, in terms of how we budget, how we plan it out, and how we manage personnel. Now we have four full 'Living World' teams that are building these content updates."
Selling Guild Wars 2 as a "pay once," then free-to-play MMO was a risky move, but it appears to have payed off. ArenaNet hopes that more constant updates will pull people back in the game more often, rather than the occasional "check up." With this much dedication, I think it may just work.
