The film will become available to the network in 2011 with exclusive US TV rights for six years. To date, Michael Jackson's This is It has made more than 200 million worldwide.

Huh? Does this mean that Sony/Columbia Pictures sold TII to MTV? Or is it more of a lease? How might this affect the release date of the dvd? I pre-ordered mine from Amazon.
