The Xbox One will require a Day One update straight out of the box when you fire it up for the first time, but Microsoft are attempting to play down the size of the thing.
"We are optimizing Xbox One so that the day one update is as fast as possible," said Marc Whitten in an AMA with IGN. "While we’re still finalizing the details, we expect that the download will take between 15 and 20 minutes for most users."
That seems a little bit vague to us, particularly given the highly variable internet speeds around the world, could MS have just given us a file size number?
Elsewhere, Whitten suggested that Microsoft will look to update and improve the Xbone's dashboard once or twice a year as they did with that of the Xbox 360 -- "Yes. Like we have done with Xbox 360, we will continue to learn from what customers want and love to iterate on the best dashboard experience." -- and he also reiterated that "neither the [Xbox One] or [its]software have any region locks".
