Source: JoystiqA mandatory Xbox 360 system update will be delivered across Xbox Live today. Although we'd love to tell you the system update will deliver a parade, like the one from Aladdin, sadly it appears to be just some tweaks.
According to Xbox guru Larry "Major Nelson" Hryb, the update corrects some Xbox SmartGlass features, an error with Xbox Music and an Xbox Video closed-captioning issue. That's it. But we're still holding out hope for that Aladdin parade.
