Gamerscoreblog has thee official word:
“Don’t worry, it is definitely still coming. Seriously, as a gamer I’m glad they’re taking the time to make it right instead of just rushing it out the door. […] I suggest you do what I’m going to do – go play some more pub games and get a ton of gold to buy cool stuff as you start the single player or local co-op game.
Having said that, as you are playing through the game, you will still be able to see your friends as glowing orbs as well as chat and trade with them.”
