time will tell if they get it into production and if it will be a money maker then.
noone is able to make educated guesses on it and even less able to make statements based on facts.
therefore its all just a huge pile of wild guesses. time will tell.
what i dont see yet is the mysterious "7e7 tech", something that came out of nowhere onto our puny planet and now seems the cure to all boeing and airline industry problems. it will also make the 747 with 7e7tech enhancement better then the a380 yet it is impossible to use 7e7tech to make the a330 competetive with the 7e7.
it is indeed a very complicated situation since no specifications have been posted yet how the 7e7tech can even make the 7e7
so i think its best to think of it as boeing having learned from its past mistakes and now introducing more modern materials and cockpit commonality and general improvements in operating costs.
so if you think about the mysterious 7e7tech it might indeed be relabeled to "boeingusingairbusconcepts" with some added "bleedless engines". however there have been nothing more then wild guesses about how it will all work without engine bleed or less bleed and maybe a spiced up apu giving the bleed with the main engines only serving emergency bleed backup.(which would after all be impossible for airbus to add to a second generation 330 since we talk about 7e7tech).
overall my wild guess is that the 7e7 just near its promised performance will be a good seller especially to the point to point priority of u.s. airlines.
i do however see airlines like JAL and ANA enjoy their first airbus sometime soon to be able to get more pax into their slot restricted airports.
same in europe.
