The details of the latest Xbox360 Dash update have been announced!

The bits I’m most looking forward to are:

• Stream WMV video from a Windows PC running Windows Media Player 11, Zune software, or Windows Media Connect.
• Play video from storage devices such as USB flash drives, Xbox 360 Memory Units, etc.
• Play video from CD or DVD data discs.
• Automatically download newly released Xbox Live Arcade trial games.

And finally:

• Optionally disable notifications from Xbox Live while watching DVD movies. (At Last!)
