I think a lot of individuals are overlooking the main purpose of this aircraft, and what it left behind. The aircraft's main purpose was to propel passenger's at a faster speed towards their location. Unintended Consequences: High maintanence, eats up the fuel, high ticket prices, and airports had to pay extra for the ability to service the Concorde. What it left behind: A status symbol, the fact that only the rich could fly such a plane, it was also a cultural symbol, and finally it was a symbol of technological progression: Our desire to go faster and faster. That being said...
I don't think that there are going to be any fast aircraft between now and 2010, yes Boeing DID anounce the subsupersonic cruiser, but that project was scrapped. If you go to Boeng's website now, it will show you the 7E7 concept which is almost a 777 but more aerodynamic (I will explain these benefits later on). If there is a plan to build such a plane, the timeline states that the plane should go into service by 2007. Airbus refuses to go supersonic and is heavily into the A380, which should go into service by 2006. In these economic times, travellers are not looking for the fastest way per se, but are looking for the most cost effective ways. Hence the more seats available, the cheaper they are (don't quote me on that one claim, I'm a bit shaky on that).
On Aerodynamics:
After seeing the latest 737, the modifications are quite clear. The wings have flips at the end. It is known that just with the flips (which make the plane more aerodynamic), the actually 737 CAN travel from New York to Japan. Hence, by making planes more efficient in its design, we could achieve greater distances with cheaper costs (which is ultimately what needs to be done). When you look at the 7E7 concept, you can clearly see that its aerodynamic. I think its quite clear that it can go far distances...
