Just after announcing the list of smartphones to receive Android 6.0 Marshmallow update, they also announced a Launch Event scheduled for October 20th. They are set launch a new smartphone with Marshmallow update. They have already started sending invites that shows a charcoal background written #BeBrilliant. Have a look:
