Having "lurked" on Airliners.net for many years and have (usually!) been very impressed by the standard of discussion - and have expanded my understanding of the airline/airliner industry very significantly as a result - I noticed that no-one has picked up on this and thought it was significant - hence a first post:
"Pratt & Whitney unit said it remains committed to developing a version of its newest engine for wide-body jets even after opting not to compete on Boeing Co.’s latest 777 model".
it appears that PW have opted out of the 777X competition - is this a resource issue for PW in that they are currently developing GFTs for a number of small/med frames or is it a size issue: that the scale up to 100k from the current contracted max for the GTF (I believe c 35k) is too big a step to be realistic in the development time frame?
As this leaves the field clear for GE and RR, will Boeing go for both or will they take the single supplier route? (presumably GE as RR are already on the competition...)
