Thankfully we've come to the point where network firmware upgrades keep the the console UX fresh. On top of that, Microsoft has been gradually adding specs to the 360 over the years. I am constantly surprised by the number of people who "just bought another one" because their previous 360 was lacking HDMI, or just didn't want to go through the hassle of M$ replacing it after falling prey to the RRoD. How long will be before M$ just says, "ok, let's add a new GPU to the existing hardware and call it the Ultra model?"
