Based on the trends in at least the US passenger industry, airlines seem to be moving more towards smaller planes and shorter hops. I don't think a new Concorde would have had any impact on that at all. If the airlines wanted a long-range, faster plane, a manufacturer would have come along and built it by now. But like the computer industry, air travel is driven to low-price commodity service, and luxury high performance air travel doesn't fit in that business model.
