Agreed.
Amazing how some walllahs think they need to design an aircraft from the ground up to have another good machine.
The 747-8 has new wings, new engines, new cockpit, commonality features and new cabin features... it's a new aircraft.
AND as pointed out, it will probably live up to Boeings reputation for aircraft which exceed initial predictions of efficiency, eg the 777-300ER and 200LR.
And when cheaper than the A380, it's pretty obvious what impact it'll have on the frogs' order books.
Yes it's true, the 747-8 will NOT have a table for the pilots to eat frogs legs off. Boohoo.
