Return of supersonic passenger travel?

Possibly.

Concorde was something of a boondoggle - an expensive luxury that used a lot of fuel and ultimately ran at a loss.

Virgin Galactic unveiled the XB-1, prototype of the Boom airliner which will seat 55 and cross the Atlantic in three hours and fifteen minutes (about half the time taken by a typical jetliner). If they can knock out the details, then the ticket price is likely to be about $5,000 - so this still won't be available to "the rest of us."

Unless they can bring down the cost a lot more. On the other hand? Supersonic jets are cool.
