Sennheiser gave their derivation in their original press release. Please
note the sad facts below.

There are 'perts with net.presence that will complain about anything,
often with no justification. And they are generally not nature
recordists. We will have to wait and see. The proof is when you get out
in nature and record with them.
The key to the newer design is the backplates, not the diaphragms. They
use a system with plates on both sides of the diaphragm, something
that's fairly uncommon. Couple that with the RF circuit and they are
unique in design. They are not the first MKH with this design, what they
replace is that design. Sennheiser's discussion of the reasons for the
design make sense to me. And I've considerable experience using MKH in
nature recording now which agrees with what they say. And that includes
my pair of MKH-80's which are excellent and qualify as one of the best
of the MKH. Go ahead and suspect the design if you wish, I'll happily
take the results.
I did finally wake up and realize that Sennheiser had the specs and
polar charts up, when I first found out about them they did not. (and
I've been a bit distracted by other unrelated events) I took a hard look
at those comparing them with the equivalent earlier MKH mics and came to
certain conclusions.
First off, the polar pattern diagrams are virtually equivalent to the
equivalent previous MKH. Except they added a line for 32kHz response.
Like the MKH-800 they do have extended frequency response though it's
not very regular. Probably more interesting is a little extension of
response at the low end.
The MKH 8040 & 8050 are a disappointment in the spec sheets. The self
noise is up by 1dBA vs the MKH 40 & 50. And the sensitivity is
significantly down. For nature recording that's the wrong way to go.
Unless some special talent in sound surfaces from them I'm no longer
interested.
The MKH 8020 is a little better story. It preserves the 10dBA self noise
of the MKH 20 while raising the sensitivity from 25mV/Pa to 31mV/Pa.
That makes it interesting to try in nature recording. I'd still like to
stick a pair in a mod SASS to compare. If they still have the good sound
and durability of the MKH-20's we will have a winner. Or at least a
improvement.
Note on the question of capsule derivation, the mics are smaller
diameter. I doubt that the capsules from previous MKH would fit, so they
are new capsules.

I expect they will still be the hand built, hand tuned sort of mic.
Parts count is not what makes the price so high. I've always believed
the reason they are so high is the customers with too much money,
however. I, too, would love for them to be a lot cheaper.
