While the biggest question concerning LG's 5.5-inch Optimus G Pro -- when will it ship in the US -- remains officially TBA, the company has posted a video preview (embedded after the break) of the software update it's sending Korean early adopters this month. There's also no launch date for the "Value Pack" upgrade listed, but the video does give a clear demonstration of things like Smart Video that recognizes when the viewer looks away using eye tracking technology, Dual Camera using the front and back cameras at the same time for stills (it previously did this for video), and Pause & Resume recording that brings Vine-style seamless video cuts. Check out the video to experience it for yourself, we'll see if LG's phablet can beat the Galaxy S4 -- and, presumably, the next Galaxy Note -- to market in the US with these features.
Update: We've got the English press release now, which details all the new features mentioned above plus a few more that are getting upgraded, and reveals the update will start going out to users on April 12th. Check out the full text after the break.
