Nevermind... [finally] got an email from RR stating that they have no intention nor authority of developing an engine for the Longer Ranged 777s. C'est la vie.</font>
I bet that would change faster than you could blink if:-
(a) Boeing decided to abandon GE-exclusivity on the variants and to invite R-R along to the party; and
(b) Trent-experienced airlines then started to show an interest in buying the new 777 variants, rather than the A340 variants which are their direct and currently more successful competitors.
