Still, my original comment that if nikon made sub 10K CMOS 645 MF system with a wide, norm, and tele prime with LS (1/500th or better) It'd drive the pricing down for the entire MF industry. If we don't need a Machine gun D4s, we have the MFD body at around the same price.
You may think gear doesn't matter, but it matters a whole lot to the companies that manufacture it. Compare the 1D X to the 1D C – effectively equivalent production cost, one retails for thousands more. Why is that, do you think? Market size. As stated above, the entire worldwide MF market is estimated to be ~6000 cameras/year. I'd wager Nikon sells far more D4s bodies than that.
Could Nikon design and produce a sub-10K MF body? Sure...but they're already losing too much money despite their best efforts, planning to lose even more would be quite foolish, and shareholders don't generally like foolishness.
Sure thats a quote of 6000 cams a year from a man who works at leica?
I'm pretty sure mass market is not in their minds to begin with.
Even if so, that 6000 Cams @ 20k+ per body, not at sub 10k. Lets see how the 645z sales go after a year and i'm sure they will sell more than that even though on a crippled lens system. Because realistically, the sub 10k body is already being done by pentax.
