Can’t say you’re surprised, can you?  Avatar quickly became the best selling Blu-ray of all time after just four days on store shelves.   2.7 million Blu-ray copies were sold in North America alone, smashing the previous record of 2.5 million units sold by The Dark Knight.  For a Blu-ray set that includes no extra features, I’d say this is quite the feat.  Click here for more information about the future releases (w/ extra features, 3D support, etc.).
