For the next decade? Unlikely. I will continue to play and subsequently purchase DLCs as they are released while I'm still playing. I never pledged for how long I will continue to support Destiny, I never said I would follow it to the end. However as long as content is added and features are modified here and there to keep the game interesting, I will probably continue to play it in my free time. The game is great so far, in my opinion one of the best shooters currently available (with an active community). Until something new and improved pops into the picture Destiny will be my go-to shooter. You have your traditional competitive multiplayer arena - The Crucible, and you have the pseudo-open world coop mode to play through and farm in that feels very familiar to the mechanics of an RPG. So until someone delivers a better shooter in either one, or both of those aspects I don't expect to be removing this game from my shelf any time soon.
