Well I think everybody is going over the top about this. Why are we celebrating a 555 seat (in general usage) airliner? It's not that great an increase over the 747, particularly if you look at the Japanese domestic models. And we all know that the interior mock-ups are just that, mock-ups that will never happen (unless El Presidentie Bliar gets one for Blair Force One)
At least they've put money in the meter now though and the new colours do look nice. Bit too Euro White though
