frame, would give the A330Neo a good chance in the market to compete with the B787......time will tell though.
If you read up on the links I provided you will see that the TEN already got quite a bit of "aid" from TXWB backports.
( Looks like the current design now is a TXWB ?scaled? core with the Fan/LP stuff from the Trent1000.)
Afaics the T7000 is a T1000TEN + more bleed offtakes. ( costing some 1/10% sfc if even that.)
A330NEO : First flight: Expected spring 2017
787-8 and -9 will have the TEN available next ~?Summer?
787-10 : First flight: Expected in 2017
There wasn*t/isn't all that much time available/left for anything else to add. ( which is OK IMHO ).
ergo the Trent 7000 and Trent1000TEN are subtypes on the same technology level.
