We saw the same with videos. Google had recognised our videos as videos (through the schema.org info on the pages), and it had been showing them as video results with a thumbnail, duration, etc., but then they stopped showing as video results, and just looked like standard page listings.
Since then, they've started to come back as video results. The way it happened definitely looked like google had rolled back something.
