Hi Stephan,
this information is partially wrong. A DSLR is manufactured in one or two production lines. This is the same for Contax, Nikon, Canon etc. They produce the number they think they can sell til the next model comes out. Only by this you get a good avarage production price.
So if you really look close to it, every DSLR, no matter which brand, is one day after its production discontinued, since it is not produced anymore afterwards. Even if it has not yet arrived the dealers
So there is obviously no new production of the ND1 planned (same for Canon 10D, Nikon D70 you name it), but this has nothing to do whether it is still available to buy.
The same is valid by the way for all bodies and lenses of Contax, Leica etc.
So there are still ND1 available and if you want to buy one, it is the best time to get great prices. But this is no indication on what might or might not come in the future regarding Contax equipment.
The websites of Kyocera are in most cases a nightmare. If you go i.e. to the German one, you will hardly find the name Contax. This is an obvious problem of lacking communication/ marketing efforts/capabilities.
You will find here more information up to date than on the official sites
