So i was thinking about an Idea for MC, and thought, What if there were cameras in Minecraft? You could keep track of Greifers and moderate your server better. You could craft them with a item that could be made like wire and other items. Then you could use Redstone to connect the camera to a TV (which i also would like added), I also thought of a Wireless Redstone Receiver, so you could put 3 of them, lets say you had a camera and a TV far apart, you could hook a Redstone Receiver up to the TV and another one to a camera and a third one to a lever, so you wouldn't have to wire everything. If they made TV's they could be used to watch something called "The Minecraft Channel" or you could connect Youtube to it and watch Youtube in a Minecraft house! Radios would be cool too, instead of the traditional jukebox you could actually connect to a ACTUAL Real life station and listen in Minecraft. All this could be crafted with "Wire" and other materials that might be made someday.
I think the Wireless Redstone Receivers would be one of the best things they could add in minecraft because most people are lazy and dont want to connect all that redstone for long distances. Another Off Topic Idea I had for Minecraft is that you could play computer servers on "Minecraft Xbox Edition" so one person on a computer could play with a person on Xbox360.

I hope you like my Ideas!
