Just looking at Johnnys-net right now, there is an announcement about what the theme song of their special drama "Saigo no Yakusoku" will be.
It will be Arashi's new song! Entitled "Sora Takaku" (空高く)~! Yay~!!
No info about when this song will be put out on CD or anything yet. But nonetheless exciting news that we'll have a new song soon :D
