Pve has always been here. Halo for sure isn't pve focused in the long run. The division seems to be going PvE but idk yet till it launches. Regardless bungie are great at pvp games, they're decent with say a campaign but destiny is much different (I know what game it is, ect ect, but maybe you won't be that milk drinker who got all pissy about what I said above). It's a mix of many things, it has no identity yet and bungie themselves are mixing things up in management because they've no idea what to do yet.
