If this is vaporware, then I wonder how I've been able to record with it (see photo). For about two years now there has been a Schoeps bar similar to the STC with 25 cm spacing and 110 degree angle between the capsules. This gives a very slightly wider recording angle than ORTF when used with 2 x MK 21 "wide cardioid" capsules on Colette cables, or 2 x CCM 21 compact microphones.
Redding Audio certainly knows about it and stocks it, and so does Jerry Bruck; he and I were the co-instigators of this product. When the first batch of these became available, I bought Jerry's for him as a gift.
Schoeps doesn't list it in the catalog purely for bureaucratic reasons--they list the STC under "ORTF Stereo," and of course when you use a different spacing and a different pickup pattern, it isn't ORTF any more. The gentleman who puts the catalogs together couldn't think of another place to list it, or so he said.
