During his Xbox Spring Showcase event keynote last week, Microsoft's head of Xbox Phil Spencer talked about future of "hardware innovation" for the console, similar to the ways PCs evolve. In a speech to reporters, he said that the Xbox One could see a future in which it is upgraded, rather than replaced by new consoles. Spencer was talking about how Microsoft has sought to align its Windows 10 and Xbox One development activities under the internal "Universal Windows Platform" while offering backwards compatibility for many Xbox 360 games, now playable on Xbox One. He was addressing the concerns of some Xbox One owners that the exclusives destined for that console are appearing on PC, thus eroding the value of owning a console.
