Shaggy sheep driver - Downfall of the Concorde.
To my knowledge the major Pax of the Concordes last flight was german leisure travellers:Costumers of a German travel agency wich succesfully offered an Atlantic roundtrip including being supersonic - some westbound and some eastbound (and opposite for the ship-cruise)!
Reducing from business necessity (and the following tricket-prices) to leisure-travellers (though in the expensive layer) IS a sign of downfall by lesser necessity!
Lesser necessity must be yet more actual today and Your wish of a successor to the Concorde may morely be based on nostalgia as well as the (high-)tech side :-/
As for a successor it's IMO morely the aim to show what can be done that drives the few plans until now, and one of this is extending the term to 'hitting the space to achieve less traveltime' as I remember.
But the WWW is still quicker and lot cheaper to close deals over, hence supersonic personal transportation is dead IMO!
