Hmmm, no file size? How do they make this 15-20 minute estimate?
I assume the PS4 will have something similar, though not as big/long as they don't have to patch out the DRM.

How large is the Xbox One’s Day One update? How long will it take to install?
MARC WHITTEN, XBOX ONE CHIEF PLATFORM ARCHITECT: 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.
