Google's next event will take place on September 29 in San Francisco, according to the invitations sent out by the company. This time, Google will introduce new Nexus devices that will run on the new Android 6.0 Marshmallow operating system. 
Until today, the preview of Android 6.0 Marshmallow was announced, and at the upcoming event, we are expected to see its official presentation.
While Google has avoided events for Nexus devices in recent years, this year we expect two new Nexus devices, the 'Nexus 5X' and the 'Nexus 6P'.
