I don't think going digital will completely kill the retail game market, due to the demgraphics. Download has killed most of the PC software market, but there are still certain applications that people purchase at the store. Nintendo has aged the overall market which means a greater portion of these new older gamers prefer to buy games brick and mortar, plus little kids still go to the store to get games. Ten years from now, it will be another story. Gamestops will change or die or get bought out, just like they swallowed up Babbages and Software ETC, who used to sell as much retail software as they did games.
