Amid all the Google Play edition news dropping today, Google has also taken the wraps off the Nexus 7 (2013) in white. Google says it'll be available in the UK, U.S. and Japan, and besides the change in color it's the same ASUS-made, current-generation Nexus 7 we've been using since the summer.
It's worth noting that at the time of writing it's only available in Wifi + 32GB versions — no 16GB or LTE at present.
For more, see the Play Store link above. It's currently marked as "coming soon" in the UK; in the U.S. it's available to order right now.
