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.
The tail assembly looks nothing like the Concorde. The fuselage owes more to the Constellation than it does to the Concorde, which was rather conventional except for the drooping nose. The nose on this plane does have the 'droop' look, but you will note that I left 'nose' off my list of obvious visible differences.
