Today Android M was listed by Google in their collection of events for Google I/O. This is Google's yearly developers conference, one where it's common for Google to reveal a new flavor of Android - or at least major updates for flavors of Android. At this year's Google I/O 2015, Google's first mention of Android M has appeared. This will most likely end up being called Android Marshmallow. Meanwhile there's a rumor that the Nexus 9 will be replaced amid some (relatively outlying) price drops abroad.
