I think cuse and coco still play regularly, I haven't been lately, but I'll start getting on a little more.
Yep, I still play PvP almost every night, and raid fairly regularly too. Haven't gotten to play the new raid but it looks great. There are now 4 raids, (the older ones aren't going to get you to max light level, but they're still fun), a ton of strikes, and all of the endgame multiplayer stuff Ivan mentioned. It's pretty crazy thinking back to how little vanilla Destiny initially shipped with because things have come a long way (in a good way) since. The Taken King, especially, had so many fun weapon quests that called for different/exciting new accomplishments.
