The Preview of Kuroshitsuji 2
It was shown at the seiyuu event on the 31st of January. It began with the grounds of the new mansion and shots of the mansion itself, we saw a white gloved hand pouring tea (much like the beginning of season 1) only when we saw the young master rise from bed he was a blonde boy. His butler who resembles Sebastian and William referred to him as "your highness". After that there was a few various shots of them in and around the mansion, one scene had the boy laying over the desk like he was either really worn out or depressed.
