IDK. DeeJ and Urk have been pretty vague on the subject, because those types of features have not been finalized. It is also unclear which features will be bungie-specific and which ones will be handled via the PS4 and X1 share features. All I know for sure is that there are features in the works and they are still behind the curtain.

Right, but the best would be that it's also easily accessible in game.
