Previously the sky dimension was planned for Minecraft. After Notch was dethroned and Jeb took over the kingdom of Minecraft, the sky dimension was confirmed NOT to be in Minecraft. Red dragons are confirmed still despite Notch "disappearing", but there will be no sky dimension for the dragons to live in and fly through. Who wouldn't want an entire unexplored dimension to fly around with a pet red dragon in? We all secretly want the sky dimension back. Who else is upset about this?
