Microsoft has said mouse and keyboard support remains a possibility for Xbox One.
However, having always been keen to keep a distinct dividing line between its console (Xbox) and PC (Windows) offerings, the company has said that it's certainly not something for the immediate future.
"We'll certainly have this great SDK for developers to do what they like. If that's something they're interested in doing, we'll certainly help them do that. You pointed out, as a lot of people forget, designing for a 2-foot gaming experience versus perhaps a nine or ten-foot experience is a little bit different. So they have to be really focused on what is that like and they're maximising for the largest possible audience.
"We kind of have this concept of when you're playing a PC game you're leaning forward. With an Xbox [controller], sometimes you lean back. You're just kinda having fun.
"And I don't want to incite the religious debate that will ensue, [but] we want to provide a gaming experience that people enjoy, certainly with Windows – that's our other large gaming platform at Microsoft. So there's something there, but right now we're really focussed on the console space."
