Most probably DX will be introduced as supported on dLive and maybe Avantis, the same way that other products from Sennheiser are. DX is the new generation and replaces G3/G4 stuff so most probably it will. EW-D series will most likely never be implemented because it cannot be networked, and it’s only controllable via Bluetooth from a phone app.
I have 6 x EW-DX MKE 2s and they’ve been great, but I miss the RF devices integration on my Avantis (I’ve been spoilt with my QLXD system). I think because it’s still early days, it will probably come out later this year.
I wouldn’t hold me breath for SQ support, it will probably be a while away still.
Would definitely appreciate support for the Sennheiser EW-DX range as that has Dante options. It is also fully compatible with the Sennheiser WSM software, so it should be able to integrate it
