From the Reuters report:
Boeing said the jet ideally would reduce fuel burn by 60 percent compared to an aircraft in 2005, but said it did not have final data to compare the fuel savings to present-day aircraft.
Oh yes they do have the numbers!!! It's just that '60%' sounds better than 10/15% or whatever it might be. That aside, it appears to be progress (state sponsored as mentioned) but then states all around the world always have.
