there are so many factors making DVD numbers smaller and smaller, and Blu-ray can't cover DECLINE of PHYSICAL MEDIA,unfortunatelly Blu-ray will never be as big as DVD were, and in coming years digital downloads will take over....I hope for sake of quality of presentation that blu-rays will be here another 5-10 years hopefully.....we should make also TOP TEN for DVD+Blu-ray, that will make better top ten to compare with years like 2007-2008-2009Marek
