Google made a big deal out of the Qi-compatible wireless charger last year, but it took months to finally arrive. This year Google's updated Nexus Wireless Charger is making its entrance in a much more timely manner. You can order it right now and it'll ship on or around November 22nd.
The Nexus charger is compatible with all recent devices with Qi technology – the Nexus 4, Nexus 5, and 2013 Nexus 7.

Back on Halloween, Google promised that proprietary binaries and factory images for the Nexus 4, Nexus 7, and Nexus 10 would arrive shortly after devices received their OTA updates. Even though some OTAs haven't even rolled out yet, as of a few minutes ago, all modern Nexus devices now have Android 4.4 KRT16O factory images and drivers available for download.
This means you can flash stock Android 4.4 onto any supported device, even if an OTA either wasn't available yet or wouldn't work for some reason.
