The flavor dependence of polarized and unpolarized quark distributions in the nucleon can lead to insights into the formation of the sea. Drell-Yan measurements have pointed to flavor asymmetries in the unpolarized distributions. Collisions at √s = 500 GeV with polarized protons at RHIC will soon allow investigations of the flavor separated polarized quark distributions via W production to complement measurements from semi-inclusive DIS. We report on STAR'S current plans, tracking upgrade, and expected sensitivities.
