Xbox One's day-one update takes 15-20 minutes

The Xbox One will require a day-one patch, and that update will take between 15 and 20 minutes "for most users," Microsoft chief platform architect Marc Whitten told IGN.

"We are optimizing Xbox One so that the day-one update is as fast as possible. While we're still finalizing the details, we expect that the download will take between 15 and 20 minutes for most users," Whitten said.

It is not clear what the specific purpose of the patch is, though a Microsoft representative said in June that this update will "accommodate the differences between hardware and software manufacturing schedules."

The Xbox One launches on November 22 for $500.
