The Google event brought the new Nexus 7 2 (http://www.gsmarena.com/asus_google_nexus_7_2-5600.php). It's a 7" tablet running pure Android 4.3 and improves the screen and chipset over the first generation (http://www.gsmarena.com/asus_google_nexus_7-4850.php) Nexus tablet. The base price is set at $230, a little higher than the $200 that the first Nexus 7 costs (both prices are for the respective 16GB model).
So, what do you get for the extra $30? A 1920 x 1200 screen with 320ppi pixel density (50% more than the first Nexus 7 and more than even the Nexus 10) for one. It's the highest resolution 7" display on a tablet. The screen also promises a 30% wider color gamut.
You also get the chipset from the Nexus 4
