Living in San Francisco, I've always been curious if GPS will eventually let both SFO runways stay open in poor visibility conditions one widely adopted. Does anyone know?

Most approaches that large airliners are doing are already RNAV (GPS) approaches. The reason they close the parallel runway is because of the current ATC aircraft separation rules.
