Today's announcement about a new lounge in Miami has this:
The Centurion Lounge in Miami joins a network of Lounges in key airports across the country, including LAS, DFW, LGA (opening summer 2014),
and SFO (opening late 2014)

I'm not surprised. A couple of weeks ago it looked like they have all sorts of construction work to do at SFO.
