Regarding the price of the Leica Q3 43 (and Q3 with 28mm). I still do think that it is too expensive. BUT we also have to compare the price to the 60MP alternatives.
Take a Lumix S1R or a Sony A7cR. Bith cost around 3.700€. Body only. If you want to have a lens in this size, optical quality and with makro feature, you will pay at least 1.500€ on top of this for the lens only. That makes around 5.200€ for the whole package without the Leica image/Leica pretender price tag on it.
Plus you might need another lens, if you want to compare it with a 60mm @31MP and 75mm @21MP. So, the price gap is shrinking significantly, if you do need to have 60MP always in each FL. you can crop of course with the others too, But not as conventient while taking the picture as with the Q3 43.
The Leica Q3 43 has additionally a 5.7MP viewfinder (Sony A7c does have an inferior EVF), has a compact and lightweight all in one solution (S1R does not), very good menu system (do not ask for Sony) and the ability to focus manually in a way, so smooth, I never experienced that with another AF lens.
The EVF of the Q3 43 is really excellent and is something you will use every day. For all these mentioned benefits compared to the "alternatives", you pay "only" 1.550€ more and will have a significant better resale value. Plus Leica increases its list prices every year bei around 300€. Since decades. This alone protects the resale value. On the downside you do not have a lens mount on a Q3 43.
1.550€ difference is a lot. Everyone has to make his own judgement. But if you shoot a lot in the focal ranges between around 35mm and 75mm and do not need always 60MP, the Leica Q3 43 is definitely worth it to compare it with the alternatives.
I was not impressed that much with the 28mm of the Leica Q3, but the 43mm APO lens in the Q3 43 is a lot more my taste. I am on the week-end in Berlin. I hope the weather is good enough to make some photos.
