Anyone that wishes to play as an Imperial will be able to upgrade from a standard account to the digital Imperial version of the game and doesn't have anything to do with Preordering on that it is bound to the Imperial collectors edition.

For anyone that missed out on the Imperial Edition at least for PC can still preorder the digital version of the Imperial Edition via online stores or direct, alternativly you could just wait buy the standard and upgrade if once you decide if the game is for you.

As to the preorder bonus of any race any faction I haven't seen how future players will aquire this but I suspect it will be a online purchase like the upgrade to Imperial.
