Google is definitely not slowing his pace in the development of Android, appeared in late 2011 Android 4.0 Ice Cream Sandwich next to Samsung Galaxy Nexus, and in July 2012 Android 4.1 Jelly Bean that came along with the Nexus 7.
But forward-thinking, we can not imagine how Google will keep the pace of innovation in its next version of its mobile operating system, which, if the search giant continues its strategy, should be available with new Nexus later next year with significant improvements.
