Default [Q] Google search horizontal apps gone?

I really liked the new interface in google search described here:
androidpolice.com/2014/05/28/google-slowly-turning-on-newer-cleaner-app-results-ui-in-search-app/
Google search has now reverted back to the old vertical list.

Everything is updated, google search is from 1/7/2014 version 3.5.15.1254529.arm

Nexus 5 Android 4.4.4, no change uninstalling xposed.

Has this happened to everyone else?
