The Queen of the Skies lives on! The GEnx-2B engines are said to make the aircraft 17% more fuel efficient than the -400 series (ref the Boeing web site). I'm wondering what would prevent the same engines being installed as an upgrade on the -400 series. Also the scalloping on the engines (also noted on the 787) at the business end is interesting - I'd be interested to learn its purpose.
Cheers
