Possible replacement of the Concord?

[Future Raptor Ace]

The Concord was a sexy piece of aerospace engineering designed by the British and French. It was the first and only super sonic (faster than the speed of sound) mode of civilian transport. Though it had its problems ultimately leading to its unfortunate retirement. For one, it was very expensive for passengers as well as other problems being fuel and loud noises/sonic booms (especially around JFK in NYC, I remember hearing its roar as a kid... very very loud!) and other vast technical problems. Well the French just unveiled a hypersonic bird (about 5 times the speed of sound, 3750 mph at altitude)..... will this be the bird that fills the void that the concord has left?
