After Concorde, who will manage to revive civilian supersonic aviation?

Commercial aircraft are flying at the same speed as 60 years ago.

Since Concorde, which made possible to fly from Paris to New York in only 3h30, no civilian airplane has broken the sound barrier.

The loudness of the sonic boom was a major technological lock to Concorde success, but 50 years after its first flight, an on-going project led by NASA is about to make supersonic flights over land possible. If successful, it will significantly increase the number of supersonic routes and increase the supersonic aircraft market size substantially. This technological improvement combined with R&D efforts on operational costs and a much larger addressable market than when Concorde flew may revive civilian supersonic aviation in the coming years.

Who are the new players at the forefront and the early movers? What are the current investments in this field? What are the key success drivers and remaining technological and regulatory locks to revive supersonic aviation?
