I would not doubt it. 🙂
Also I think the evidence is now clear the M10 sensor structure as a whole does have fundamental differences from the SL, notably the CFA, which RAW analysis of color matrix from M10 DNGs suggest.
So I'm now of the belief there is more than algorithms between the SL and the M10, and I'd support your general contention the M10 is a "new" sensor in broad terms. The actual naked sensor could still be identical to SL of course with a new CFA, but I think it meets the criteria of Leica's claim which you have loyally supported.
Forgive my skepticism, and it's not the first time I've been wrong in a discussion with you: I must thank you again for waking me to the fact the M9 and M240 are essentially the same size, despite the misleading specs which are spread everywhere. I was a little stubborn there too, but I verified it and would have continued in the mistaken belief without your pointing it out. I've also been informed by many knowledgable posts from you on Leica related subjects over the years, thank you 🙂
It's a new sensor, both in output and at very least, the CFA, which is pretty fundamental, more so in my mind than the IR cut choice.
That is exciting. 🙂
