So this is interesting, Google just updated the product page for every Nexus 7 model on the Play Store, and the change on every one is the same: estimated battery life. Previously, the Nexus 7 was listed as having "Up to 8 hours of active use," but now the figure has been revised to 10 hours - within a day's time of the release of the Android 4.2.2 update (manual update download here).
Update 2/13/13: Google just reverted all the Nexus 7 pages back to 8 hours. Why must you toy with our feelings like that?
We've been digging for new features and changes in Android 4.2.2 (see here, here, and here), but we've yet to see anything specific about improved battery life.

Android 4.2.2 is out, and while an OCD-fueled 4.2.2 edition of Getting To Know Android is on the way, we figured it would be a good idea to highlight the big user facing changes that came with this release.

until completion. Uses a moving average that is weighted 1:1 with
the most recent 500ms sample. Funnels timing data to notifications
