This does not answer the question.

We all know Sonos consciously chose to disable it with the explanation being “we know better than you.” Let the customer decide which experience they enjoy the most.
As the video conveys, Sonos have disabled it through software. For months users have been insisting that they enable the center in surround mode. I want Sonos to stop dodging the question and tell us when they will make this change. If it will never be enabled, communicate that so I can choose  a different product which fits my tastes. 

Sonos never reveals what it is currently working on, so I would choose a different product.

And that is why I am sticking with my Ones until I hear a definite answer.
