Other updates include the new UI and greater content for Asus Vibe which is changing from 1.0 to 2.0, the change in the Android Market, Google Books and Google Music to their proper Google Play counterparts, and an update to the camera that will allow a future firmware update to imrove the ol' shooter. After the update, you will be able to hook up your tablet to your television via the HDMI port and view it in landscape or portrait. Finally, you gain the ability to support USB LAN connections by using a USB-to-Ethernet UX cable.
You might not have that long to wait for the update as it is expected to roll out in some regions on Friday.
