What is the advantage that the 7E7 or the Dreamliner have over
the rest of the line?

I assume that the market niche for the 757 and 767 is still
there. It is just that they are not large enough to support the
lines or just use other aircraft to cover that niche.

7E7 will offer airlines a new airframe (they can't fly the same old ones
forever)

No ?

My fave large a/c is still the 747 ( not keen on 777 - feels cramped to me - and
I'm sure that factor will be a great seller for A380 ) . 747's been around a
while hasn't it ! ;-)

Modern version of 737s still sell well and how old is that design originally ?

Even some ancient 727s were only recently pensioned off in the US.

with what is promised to be unparalleled efficiency. Airlines have
to maximize efficiency in order to remain profitable. Note I got my
replaced-airframe list off-kilter (see other message in this thread).

Fuel efficiency ( cost per seat-mile ) is what it's about. This factor is
skewed by amortised cost of old but serviceable a/c - like the 727s I just
mentioend. Not efficient - but the lease purchase was paid off decades back.
