It's shrinking for sure! That's obvious any time any game comes out on console within the same genre players will leave. Eventually, a game will "die". However with titles like Destiny the more [b]quality[/b] content that gets added in consistently will keep the game going until its' sequel is released. However especially right between and leading up to these updates players will go to something else. Especially now that it's the Holiday season. Even as I say all this you know a few of them or a good chunk of them will return, maybe not for a long period, but they'll be back now and then to check up on things.
