Considering Quattro H concerned about SA lenses

I owned at least one of every generation on DPX camera. My most sold landscape photo was taken on a DP1s. My Merrills are getting on and I am considering the Quattro H. I recently bought a Sony A7rii ($1600 new), Loxia 21mm, and Zeiss 55mm. However, I wasn't happy with the IQ compared to my Merrills and am considering returning it. My goal is to print A0 and even larger.

Now, the Quattro H is on my radar; but, I am concerned about the SA series lenses being discontinued. I don't want to invest in an already obsolete system. To those maybe more knowledgeable about this:

- Is SA dead?

From the horse's mouth:

As part of its move into L-mount cameras and lenses, Sigma will be turning its back on its own SA-mount cameras (though it will continue to produce SA-mount lenses).

“All future interchangeable-lens camera systems developed by SIGMA will feature the L-mount,” Sigma CEO Kazuto Yamaki says in a statement. “SIGMA does not plan to develop new cameras equipped with an SA-mount.”

Photographers who have already invested in SA-mount lenses will have the option of having them converted into the L mount. There will also be an SA-to-L adapter for non-converted lenses.

“SIGMA treats our continued support for SA-mount lenses as a top priority,” Yamaki states. “This commitment of ours will not be affected by our move to a new mount system, and SA-mount lenses will continue to be part of our production.

- What lenses can be adapted to fit the SDQH?

Question is too broad for me to answer, sorry ...
