A healthy stream of leaks in the last several months indicated that the latest version of Jelly Bean was right around the corner, and at its press event today Google pulled back the curtain on Android 4.3. Unsurprisingly, the latest-gen software will debut on the new Nexus 7, which was also announced on stage. In addition to shipping with that tablet, the software will be available as an over-the-air update to latest Nexus devices today.
