There is a well publicized theory that the birth of the 777-100X will mean
the death of the 767-ERY.  The aircraft would aim for roughly the same
market segment and that would be counter-productive to one if not both
of the models (just ask Mazda about its 929 sales since the introduction
of the Millenia).  The -100X also makes more sense from a technological
point-of-view because the 767's design, avionics, etc. are approaching
20 years old.  It would be far more logical to derive the new ultra-long range,
low capacity aircraft from the more modern predecessor.  This would allow
the manufacturer to take advantage of its more recent advances in aviation
