The PC cannot currently play non-ported Xbox games at this time, though. I get why you’re saying “just a PC” but that’s a distinction worth noting. I hope the PC platform in general will gain the ability to play all Xbox games and not just Xbox branded hardware. I also hope PCs gain the ability to use some of the features that are nice about Xbox (mainly Quick Resume).

Could be that they add that functionality into Windows, though. There’s nothing special about newer games that run on Xbox, they’re all x86 applications. Microsoft could just release the Xbox middleware as its own app and allow Xbox games to work on whatever PC it’s installed on, which is basically all that an Xbox is right now.
