We can always hope. The last news from Michael2 was that he's a young father now and that all tuning and tweaking is based on the 'as time permits' basis. So that's a thing to keep in mind. However, that's from some months ago.

On the actual problem with e. g. EPR readings, he had some tweaked gauge on the 727. So it got replaced and then delivered better values together with the other teaks of his. Now the 707 comes with 3D gauges and a change isn't that easy to do. I think he actually tried and received very funny pointers on the gauge itself.
In my humble eyes, the FDE tweak on the 727 helped a lot, while I think that the default 707 already gives a nice feel. So there may not be an urgent need.

However, I'm glad to read about some fans of his work. That's the best appreciation one can get and you folks can count me in.  :)
