A bit of LG Technology coming the other way might be a nice surprise.

If LG can fit the Atmos processing into something like a sound bar, it's not too unreasonable to suppose that they could feed the height channels from the soundbar and have some sort of Meridian 'output' that could send 5.1 to the Meridian processor.
