RC, I too am seeing a more varied SERP, and I'm in the Los Angeles area.
That said, what Brett posted looks a lot like when I search for my no-site-link domain names as "my domain." But my domain name is not a keyphrase - it's a brand, so it doesn't have any real competition for that phrase, and anyone searching "my domain" IS looking for results from my domain.
That makes me wonder if one thing Google's testing is how it weighs domain names in queries.
