Android 4.3 Jelly Bean Breaks Cover in Listing For LG Optimus L7 2 Smartphone

Of course, this could just be a misunderstanding, or even a typographical error. That said, v4.3 is listed twice on the page, so it stands to reason that it was placed there on purpose. What's also odd is that a phone with an Android overlay would be listed with an advanced build; typically, Nexus devices are the first to receive new Android builds, with skinned phones receiving those updates much later.
This Youtube user video purports to show some of the features of the camera enhancements that could be coming with Android 4.3.
Perhaps this is all a sign that the Nexus 4 will be seeing a new build of Android in the coming weeks?
