Im wondering the same thing still

As i have a 1.0 account from when i played a free trial and bought the collectors edition of ARR and i dont know if there is a way to use the collectors code out of the box on an existing SE account to gain the items

Although i am sure someone mentioned they are looking into this?

any confirmation would be great, as i dont want to pay for the digital upgrade when i have a code for the pc version of the collectors edition!
