I wonder if there will be a D3 authenticator like WoW. I know piracy is a big deal and its great to see them taking a step in the direction of combating it. But if you are trading using real world money, it will make D3 even more of a target to all the account hackers than WoW. And I know in WoW I played for a month, for the refer a friend promotion and I had my account hijacked 7 times in that month. Twice in one day even. And this is without going to all these funny sites or installing strange programs. I know a lot of people might think twice about using real cash for items, especially if there is no improved account security. So the auction house for gold might just as easily house some of the top items in the game
