Well in honesty don't you expect to buy 2 different version of a game if said game was aviable for the ps3 and xbox? I'm assume you do. So why would this be any different I was honestly suprised that we will be getting the Ps4 version of the game for free if you bought the ps3 version. I am sure though you would need to buy 2 copies of the game when expansion comes out. To prove that each account had actually purchased the game. I do understand why they do it. Its to stop people from buying one version of the game then handing out to friends to install, and then just purchase a subscription. The company would lose a ton of money if it was that way.
