I just watched the last few minutes of the diy program where they were showing new tools. They had a cement cutting chaign saw. You hook a water hose to it and it has a mud flap to help keep you dry. It will cut concrete 16" thick. It will cut through stone and rebar. I called a friend that owns a fence business and a tool rental. He looked at one and found it has a few drawbacks. First the price about $1,600. Very heavy and a lot of vibration. He also found that if you cut through the concrete and get into dirt it is very hard on the blade. The dirt wears the steel behind the teeth making the teeth fall off. Also when cutting the rebar it tends to dull the blade and replacement blades are very expensive. He is considering getting one but if so will only rent to licensed contractors. He does not think it is for the home owner. He probably would rent the tool and operator to the home owner.
