Friends at Kotaku and Engadget are claiming this unconfirmed video is of the XBox 360 Spring Update. There's lots of detail here...unconfirmed detail...but the most important unconfirmed tweaks are:
•Unconfirmed integration with MSN messenger by way of friends list and on screen chat pop ups
•An unconfirmed live download mode that puts the console into Jedi sleep
Off the record, let's be honest: It looks real to me...unofficially. But until official confirmation, it's all officially speculation. Got it?
