Or maybe read the thread.
Care to provide a quote or link? Last I recall was Colin mentioning in December or January that concurrency had dropped a month or so after launch which was expected and that they had consecutive weekly increases for several weeks before that interview. Haven't seen anywhere that someone from ArenaNet said that "majority of people don't play it anymore". Haven't seen any sales figures since the 3 million announcement either. Would be nice getting an update on the numbers.
Edit: found the article. It was a bit later than I thought, from 1 Feb 2013. http://www.pcgamesn....-living-stories
