This plane is another Concorde. It will be a disaster for Airbus. We should hope that they build plenty of them. They will find few markets for them as it is a obsolete solution.
Also being overlooked is the notion that the airlines are largely going to smaller planes as a result of industry dynamics and the rising cost of fuel. They simply can't afford to run half-empty planes across the country. So Airbus apparently is fighting an economic battle indirectly as well. Perhaps the overseas markets are different such that greater sized aircraft are practical, don't know.
