So far, there has not been any reports concerning the updates that are rolling out to the Wi-Fi Nexus 7 or the Nexus 10, so it would be safe to assume that there will be some bug fixes in the update which have something to do with mobile connectivity. It might also be presumptuous to assume, but we are going to go ahead too, that the camera fixes for the Nexus 5 too, might not make its way down to the rest of the Nexus family. Some folks have reported that sideloading the Android 4.4.1 update on the Nexus 4 did not yield any difference in the camera, not to mention the alleged new progress bar not appearing when snapping a HDR image. The manual update packages for the Nexus 4 and Nexus 7 can be found here and here, respectively.
