It seems to me that, aiming at over-simplification as usual, they managed to produce exactly the opposite result: items of very different nature (system prefs, hardware and network status, system actions) are conflated in a single menu so that the user has to hunt the desired information while before you simply had to look for the corresponding icon on the status bar.
Already confusing clutter as is IMHO, but wait until you also have Bluetooth, Dropbox and more stuff crammed into that menu.
This judging from the release notes screenshot, ofc, since I don't have GNOME installed on any of my boxes.
