In a earlier question months and months ago.  A person asked a question about sonos fully supporting era 300 inverted as surrounds.  A rep from sonos said that sonos will be fully supporting that feature soon.  It has been quite a while since then.  If a person from sonos directly can address this,  then that would be greatly appreciated.  Is inverted era 300 still happening? Is it happening soon? Is it happening not soon? Thanks
