Currently, on Netflix, there are 9 seasons of Grey's Anatomy available for streaming. That is 196 episodes. Without commercials, each episode averages about 45 minutes. This would take you 147 hours to watch all current episodes. This is a total of 6 days. Add it time for sleeping and eating, and it would take you about 10 days if all you did was watch Grey's Anatomy, eat, and sleep.
October 2012 but no definite date according to dvds-home.net greys anatomy season 9 come out on dvd wil be the same time with the season final.
