There's some new firmware floating around updating the GoPro HD Hero. The new firmware update will add a ton of new options making a good thing even better. The most exciting feature is the 'Live View' feed. Plugging the GoPro HD Hero into a monitor with it's composite out is said to even provide 'HD' feeds for live viewing. I've gotta try this when I get home. You can find more information about the new GoPro firmware at their product website here: http://www.goprocamera.com/support/hdheroupdate.php
With this new Live Feed out, there's also a new housing to support the cable connections. I'm still waiting on the external battery pack and mini LCD.
