Sony Fails AGAIN to deliver the Marshmallow OS update in March

Sony AGAIN fails to deliver the Marshmallow update for the 2015/2016 Sony Bravia 4K HDR TVs in the US. What is going on Sony? This update was suppose to be available 4 months ago (after 1 year waiting for Sony committed to do so) - That means that all Soy Bravia 4k HDR TVs will have at least a 3 Android TV versions gap. I wish that Sony would take this TV business more seriously.
