To create a little parity I was wondering if you purchased the XBO (or PS4 for that matter) and wanted a second copy for your last gen console (I have mine still and imagine others do as well) and if the account is shared within the XBOX family this would allow us to have one playing on the XBO and one on the 360 (separate IPs so they can share the XBL account without IP conflicts in my network). Just a thought because when I heard about this, after pre-ordering the Digital Guardian Edition for XBO I wished I had done that for my 360 so I would get two copies for the price of one.
