To me, mirrorless format is superior. Anyone buying a new camera is probably taking a look at the newer models.
You can pry my shutter sound from my cold, dead hands, though.
Luckily sounds are easy to synthesize.
I think for the most part I'd agree with you, there's definitely a lot of upsides in mirrorless systems, especially in terms of flexibility. I will say though that the screens in mirrorless EVFs are often lackluster in comparison to optical view finders in my opinion. In particular frame rate of the EVF is problematic for me.
