The Destiny disk currently in your console will not be constantly updated for 10 years. Bungie and Activision simply signed a contract saying that they will work on the Destiny franchise together for 10 years. That means more games (prob Destiny 2 and 3, at least) and countless paid expansions throughout the next 10 years. You didn't just pay $60 for a 10 year game. You basically paid 60 for a demo of this supposed 10 year franchise, and they're already promoting the hell out of these expansions that we have to pay for, just so we can finish the incomplete story that we just dropped $60 on.
