It'll be a kick-ass aircraft, but it's interesting that they are going for reduced weight and thrust.
Surley save the weight, but leave the engines at 115 and the MTOW at 351, and so reap the extra useful load.
You MIGHT end up a touch heavier and burn a little more, but if they can make money out of the A380, surely load is more important than burn.
-and lets hope Boeing sacks up and tells EK they can't have it without the proper Pilots CRC!!
