Nintendo was sort of doing this more than 20 years ago via FX chips and N64 expansion paks. The difference of course, is that Nintendo sold one machine and used other means to pull off the upgrades giving consumers the feeling of a uniform platform.
Microsoft has lost it's way, totally. It's no longer interested in "console gaming" imo. Their hopes of changing the way the industry does business is probably a sham intended to distract everyone from their shift back to PC.
