Engadget sat down with Aaron Greenberg, Microsoft's head of Xbox games marketing, to talk about Xbox One, Project Scorpio and the future of console gaming.

"The future of Xbox looks a lot like PC gaming." That's what Engadget editor Nathan Ingraham wrote after speaking with Phil Spencer earlier this year. Spencer spoke about wanting to see a steady stream of hardware innovation rather than seven-year gaps between consoles, citing the smartphone market as inspiration. Greenberg went one step further. In his opinion, this is the last console generation. "We think the future is without console generations," he said, explaining that Project Scorpio was a "big bet" that gamers will embrace that notion.

Q: The Xbox platform has moved forward to have such regular updates and new features coming all the time. It kind of seems like hardware is going the same way. There was a very short gap between the Xbox One and the Xbox One S, and we're probably talking an even shorter gap before Project Scorpio. Do you see a future of console upgrades continually happening? Is this the last console generation?

Greenberg: I think it is. ... For us, we think the future is without console generations; we think that the ability to build a library, a community, to be able to iterate with the hardware -- we're making a pretty big bet on that with Project Scorpio. We're basically saying, "This isn't a new generation; everything you have continues forward and it works." We think of this as a family of devices.
