Class D amps seem poised to take over. Then what?

What you posted shows lack of knowledge. Your talking about products that you have zero knowledge about, why say anything at all?

I hate it when people talk about subjects they know nothing about.

Never entirely but for the most part, class D is too attractive an option to audio manufacturers with it's cool running efficiency, compact form factor, etc.
Properly implemented, it's increasingly recognized as being as good or better than the alternatives, despite myths to the contrary.

I have been selling audio for along time now and we have heard this type of rhetoric before. A few decades back a person buys a cd player and claims to the world that the turntable will now be obsolete, more recently another person bought a streaming device and declared to the world once again the turntable will be obsolete. The names change but the story its still the same. Very seldom do our customers every make a request for a certain class of amplifier, instead  their decisions are based on how it sounds with their equipment and room. Class D amps have made themselves known in the huge audio equipment landscape, are they going to make everything else obsolete? History says no. For us the problems we have encountered with class D is reliability and repair

I hate it when people talk about subjects they know nothing about.

You need to hate yourself then, as you have no idea about the performance of Class-D even when using GaN Fets into 8 4 2 and 1ohm at it’s "current ability" (wattage doubling) at these loadings. And how those Wilsons demand it to get the best out of them.
Next you’ll say an OTL of Ralphs can drive those Wilsons to their best properly, because they too will stay stable into them and not oscillate.🤷‍♂️
