Hi--
I can see why you have questions. When specs are
loosely defined, I tend to not get optimistic,
but some Sanken mics are highly regarded, often
by film and video folks. We've found that
comparison tests and field use are the only
certain way to assess performance. Here's a
search of the mic(s) on the rec.arts list:

Self-noise is important, but not as crucial for
most film/video applications. I believe the Rane
Notes suggest that (A) weighting usually lowers a
self noise number around 7dB.
The stated sensitivity of 70.8mV/Pa is notably
high when the two mics are in the "wide stereo"
mode. Then statement strike me as curious: "The
WIDE mode is designed for stereo recording of
sound effects where dialogue will be dubbed in at
a later date. This mode allows a wider 140 degree
pickup, whereas conventional M-S microphones have
a maximum of 127 degrees."
Is it doing internal M-S mixing? Can the signal
from the two mics be recorded discretely?
Also of interest to nature recordists "... with
new PPS ( Poly-Phenylene-Sulfide ) diaphragms to
provide optimum humidity / temperature stability.
