Free? lol.....They've seen how much money they can make by charging $5 for a stupid dance emote, there's no way the expansion will be free. Not getting my hopes up from a few vague sentences though, wouldn't be the first time they generated a bunch of hype and failed to deliver...If they try some $40 bullshit like ttk I don't even think I'll bother though, too many other games I'll be playing by then.
