Part 2 of the Xbox only One Update

“We still believe Kinect is a really critical part of the architecture,” Whitten explained. “We think it changes the way you can interact with your experiences, being able to control the box with your voice or with gestures, being able to do Skype. And we want game and interactive entertainment creators to be able to know they can take advantage of it, and we want it to be completely consistent for our users. So we still are very committed to how Kinect transforms that experience.”
Whitten clarified that “you’ll still install [games] to the hard drive. Obviously if you download them from online that’s the way it works. If you put a disc in, it will install it to the hard drive. You will have to have the disc in the tray in order to play. One of the cool features that actually comes with that, as an example, because we built on all this infrastructure around Xbox One, is if I went to your house with my disc-based game and we played for a while, and obviously I’d installed and we played, and then I left with my disc, you could instantly buy that game with no downloads.”
The instant game switching that Microsoft showed off at E3 will also still function, though players will of course need to change physical discs if they’re swapping between hard copies of games.
“So much of that still works exactly as we’ve been describing,” Whitten clarified. “You’ll instantly switch between the game that you’re playing, between television and apps, between Skype, you’ll be able to snap those and move between them effortlessly. Now, if you’re talking about disc-based games, because the disc does have to be in the tray to play, if you decide to switch to a disc-based game that’s not the current one in the drive, you’ll have to go get it.”
“And you’ll also, in the middle of your disc-based game, you’ll be flipping to the web browser because you want to do something or snapping to Skype or flipping over between live TV and then going back to the disc-based game,” he continued. “So that fast and fluid experience, which we think will define next-generation entertainment, is still a core part of how Xbox One works.”
