5 out of the top-ten grossing movies so far this year are Blu-Ray exclusive. 3 are (now) HD-DVD exclusive. Two are format neutral. Interesting.
Also, Paramount, on the last line of their press release, states that their exclusivity on HD-DVD does NOT include Spielberg movies. In fact, his first movie released in high definition will be released on Blu-Ray, Close Encounters. That also means that the Indiana Jones movies, if they ever come to HD, will be on both.
