Unsurprisingly, your Xbox Live Gold account will transfer to your Xbox One should you choose to purchase on when the system is released later this year.  However, the exciting news surrounding this revelation is that one Gold account on a system activates Gold for all users on said system.  This is a great and welcome addition to Microsoft’s pay-to-play online service and should reduce household costs for Gold accounts (unless they decide to raise the price of Gold yet again).  Gold access will be granted to multiple users’ accounts and will enable the same features and benefits to all users while allowing them to maintain their own saves and friends lists.
