For that same search I am seeing a different, new mobile 3 pack like display test (using Firefox) on the desktop. Interestingly the mobile like three pack comes with links to the new Local Finder that rolled out with the Snak Pak update in the third week of July. This new display is consistent with Google’s Material Design standards.
As Google + continues down the debranding path, I assume that we will see the complete disassociation of local results from it and the integration of the Local Finder instead.
The Local Finder essentially replaces the old Map list view with a light weight business listing focused display that works much better than Google Maps for discovery type browsing. It makes sense to me that it would become integrate with all local results and not just the snak pak.
