Mantelmount released the MM850 at CEDIA. Motorized, in-wall recessed, IP control including Alexa, auto-retract with temp sensor (in case it gets too hot), etc. $1699 MSRP. Not bad. We have one of the manual models on demo. It works great, I only wish it had a "soft close" feature. If you let go of it on the way up, it will go quickly and bang to a stop.
