"Wii and PSP saw an increase in sales week on week, while all other systems are down. The Xbox 360 is now the only system up year on year as the PS3 received a massive boost one year ago due to a price drop on the old model and some retailers releasing the PS3 Slim a week early. Week on week software sales are up for the Wii, Xbox 360 and PSP while down for the PlayStation 3 and DS."
