njw1, this is a user to user support forum so nobody here will have any knowledge about the wall bracket adapter support for the newer iMacs. You will have to contact Apple Sales department directly in regards to your question. Good luck!

The item is still there see
but it only shows compatibility up to the 2011 27in iMac, the 2012's are listed. This may be an over site or it may be that this doesn't work on the new models.
The plate was attached by removing the iMac stand so I'm not sure the change in the edge dimensions of the iMac should make a difference, the stand looks the same.
I would suggest contacting the store and asking.
