Yeah I'm still gonna jump on a couple times a week. I will still wanna throw my hammers around. But I think the first month it will be only Destiny 2 for me. Once I get all 3 characters through the story and start the endgame content I'll take little one day breaks to go back to Destiny 1 and mess around or do a raid. I know a good chunk of players will leave when Destiny 2 comes out but there will also be people who are going to wait until Christmas (most likely the kids that can't buy their own stuff or people waiting for a cheaper deal), people waiting for the collection, and people like me who will go back occasionally to play their favorite classes (Sunbreaker, Nightstalker, and Stormcaller).
