Aye, it's been out for a while now. Released by Universal. Pretty substantial improvement from the dvd.
According to Play, Optimum are releasing the Wicker Man on blu on March 2010. Will probably be the shorter cut, as I think the full version only exists in the form of a one-inch telecine master, sadly. Great film in any version though, with a really memorable performance from the late Edward Woodward. RIP.
