Looking at the graph as of October 17th the daily pvp population will soon plummet under 1 million with the pve population soon following, in the video the dude said that Bungie was saying how Destiny 1 had a daily population of over 3 million concurrent players for 3 hours a day, so if I was Bungie I would be asking myself what it was about the House of Wolves era that motivated mass amounts players to consistently play the game then work on providing more of that experience. Easier said than done, but if 1 month in we are about to drop below 1 million concurrent players (with the exception of the pc crowd that's about to get a hold of the game) I would be concerned with the future of this game and the potential future sales of dlc.
