Koji Kondo Composed for Skyward Sword. He seems to mainly act as a 'sound supervisor' and a 'sound adviser' these days. (Such as in Mario Tennis(Which is composed like all Camelot games by Motoi Sakaruba) and Ocarina of time 3D).
On a whole he has seemed to have taken a step back and is hardly involved in composition anymore. He mainly does work on Mario titles and spin off (He's contributed to all the Smash games) and Zelda titles. However he has composed on all Zelda titles other than Phantom Hourglass since LTTP.
So not retired yet, just not as prominent as he once was.
