Boeing has been reluctant to launch the B787-1000 which would more closely meet Emirates requirement.
read as: Boeing was "reluctant to launch the B787-1000" at EK terms and price expectations.
The profits Boeing will get on more sales 777-200 plus 787-8/9 to other customers at this point are more than the 787-10 profits from EK. Reality sets in the universe does not always rotate around what people in Dubai want.
Airbus is struggling with the A350 and will bend over backwards to get a big order form anyone at this point. EK stepped in to save them again just like the A380. And Yes it will all show in the bottom line for EK.
