Also, you can always count on some big announcements. In 2012, Google introduced Jelly Bean, TV shows and movies to the Google Play Store, Google Nexus 7, the Nexus Q and went skydiving with Google Glass. Last year's show was held in June but this year the event will be held one week before the CTIA show in Las Vegas.
Google usually releases an app that makes navigating the event easier. Stay tuned!
