Looks like Concord

Except for the engines, wings, tail, fuselage and canards.

Actually the fuselage, vertical stabilizer and nose are similar to the SST. It's interesting too that the nosewheel is located so far back, again similar to the SST. I have no idea how far along this design concept is, but the SST had a very sophisticated fuel management regime to shift the CG fore and aft depending on the phase of flight it was in. I kind of wonder if this one has to jump through the same hoops, or if they've broken new ground in supersonic flight.

He meant optimized for supersonic cruise I think :)

One thing Boeing does better than anyone else, optimization of all the conflicting/competing variables to make a vehicle like they do.

You can go all the way back to the B-17, and see that in play.
