I was browsing around Wikipedia and noticed they finally updated the SA MSA TO SA-NB MSA according to the new 2010 MSA guidelines.
"San Antonio–New Braunfels is an eight-county metropolitan area in the South-Central region of Texas, centering in the city of San Antonio. The names Metro San Antonio and San Antonio Metro are sometimes used when referring to the MSA. As of July 1, 2008 the metropolitan area's population stood at 2,031,445, up from a reported 1,711,703 in 2000.[1]
The San Antonio–New Braunfels Metropolitan Statistical Area is the third-largest metro area in the state of Texas, after Dallas–Fort Worth–Arlington and Houston–Sugar Land–Baytown. It is also the fourth-fastest growing metropolitan area in the state, after Dallas–Fort Worth, Houston, and Austin."
