I don't know why I bother to reply, but, anyway...
Originally posted by Uluru 6 months delay is delay by design, not by a missing part. Japanese have introduced to the world many concepts, and meeting deadlines is one of them.
There is no way any planing or design has been done before thorough discernment about dates, checked at every step of the production.
Sloppy westerners may think by default this is some kind of normal postponement, but for anyone who has ever visited Japanese factory, no, it is not. This is impossible to happen. 1-2 months are hardly allowed in any out-of-ordinary circumstance, but 6 months?! Only a tsunami or a volcano eruption in the backyard can postpone something 6 months in Japan. Or something done by design to buy necessary time.
Therefore most of forum members who are not Japanese think of all sorts of crazy excuses typical to their cultures, but I am 100% certain this is a deliberate decision. In short, Ricoh was almost 2 years too late to the FF market explosion, but needed to address 645Z first to steal FF craze some thunder, and then, of course, came too late with their own FF to keep own customers changing systems. And to address English speaking users, they came up with a strategy suitable and plausible to their mindsets.
And you are buying it, big time.
First targeted availability: End of 2015 = everything before January 1 2016. Updated schedule: Spring 2016 = starts at February 5 2016
You hyperbolically speculated and concluded, it can only be because the lenses are not ready -> on Friday the dedicated normal zoom will be announced, a tele-zoom is ready and another one also in spring, beside some other lenses who will work with the camera.
Now you got inspired to even more wild speculations presenting them in a voice far from polite, and healthy. Draw your own conclusions, it was nice to have read you.
