DekX, the current 7E7 illustration still shows a profound curve to the tail. Until Boeing publishes a revised one with a completely straight-angled tail, I accept the possibility that the 'sharkfin' could still be in the final design.
Antares, while at least some of your authoritative assertions could be true, if you can't name your source, how do you expect us to take you seriously? Making claims without substantiation is a waste of both your and our time. We all know some of the more unique design elements might be conventionalized out of concerns for practicality, maintenance, etc. Yes, the tail might get straightened, the window height clipped a bit, the forward windscreen reduced in size from the early pictures. But comments like this...
"Next 7E7 feature to take a hit MIGHT be the electronic window shades. And after than, a steep downward revision of the percentage of composites and a humungous dirt fight with some of the suppliers who can't deliver on the new technology."
...are sheer speculation on your part. Substantially reducing composites would undermine the business case for even doing the 7E7; its rationale was based on reducing a lot of weight, compared to current like-sized jets which is critical to its mission. The electronically lit 'skylights' you say were axed, were a major feature of the 7E7 mockup I visited in the a.net organized tour that included the Boeing Design Center. The focus was to provide passengers with a comfortable flying experience in which the skylight provided varied lighting which could simulate day or night or adjusted to illuminate the cabin with colors to enhance mood, particularly useful on long flights. It seemed absolutely feasible and isn't Singapore using some variation of this idea on their ULH A340-500 routes? Unless airlines balked about whatever it cost, I'd doubt Boeing would have backed away from it already. The bottom line is: until we see this from an official source, it's all hearsay, not the gospel according to Antares.
Second childhood, eh? Sure you're not confusing it with Althzheimers?
That crankiness might be an early symptom.
