Received my 2nd Studio Display today and have had time to use them for a while. The second display hasn't prompted for a firmware update so I wonder if the first display updates it, the Mac updates it, or it just hasn't prompted me yet.
Overall they are great however there is one issue I noticed straight away. If you have you Mac Studio underneath your display as Apple has shown, then you will be impairing one of the speakers. As soon as I started playing music I noticed it as there is less room for the sound to escape on the side you have the Mac.
Also it is not possible to use the speakers in both displays at the same time as far as I can tell. Because of this one of the displays speakers will be completely redundant. This is especially strange when you have sound coming out of one display but your YouTube video is playing on the other (silent) display.
Build quality is as superb as you would expect and they look amazing.
