Microsoft’s store in Sony’s San Francisco Metreon complex is closing and will be replaced by a non-Microsoft-centric tech emporium. One article says the reason for the closure was lack of business, with both companies deciding it wasn’t worthwhile continuing the endeavor. Another hints that Microsoft’s upcoming release of the Xbox entertainment console, a direct competitor to Sony’s Playstation line, had a lot to do with the agreement that the store “sort of became not-a-fit anymore.”
