Highlights from GameStop's (GME +0.6%) presentation at the Goldman Sachs Technology and Internet Conference: 1) The company will close unprofitable stores at a faster pace than it opens new stores across the world. About 80% of the stores slated for closure will be in the U.S. 2) On used games, CFO Rob Lloyd says publishers still want the used game model because it puts cash back into customer hands. 3) GameStop says it will maintain its policy of returning 100% of free cash flow to investors through dividends and buybacks. 4) The product pipeline looks promising, particularly in Q3 with a new Grand Theft Auto release scheduled.
