TTK will be updating the entire vendor thing. I don't know if faction quests will finally be in, but they're changing how the gunsmith and Eris act in the game. Osiris will have it's own bounties while Crucible bounties are getting changed up. A ton of Exotic itmes are being added. Bubgie inferred more quests would be updated in and the ones we get with the DLC are just part of the "first act" or whatever they said. Three new strikes on top of updating all the PS exclusive strikes with a Taken-ified version. So technically six new strikes incoming. Only one patrol area with Phobos probably being explorable. The Dreadnaught patrol is supposed to be bigger than any current patrol (which doesn't seem very hard to do). And the patrol should have hidden bosses and stuff in it to find. The Oryx raid should be bigger than Crota's and hopefully VoG. Along with eight new Crucible maps and a bump up to a level 40 cap. Also, new subclasses.
