I am seeing the same thing with my hobby site. My rank (for a specific two word query) is the same, even when I use a proxy to check several Geos, but traffic is way down. Overall Google traffic is down less than 10%.
In a more competitive niche I am seeing the Geo dial turned way up. This has been a pretty consistent SERP for the past few years, but over the last few days (maybe a week) the SERP changes dramatically with location. Also, no Google local results just local pages.
