It seems as though most people didn't read the full story, but rather just the tiny bit that was quoted.
Whole story is quite interesting, although I'd love to have a better translation than Google.
Things I THINK I gleaned from the translation.
Canon is not unaware of the needs of studio photographers but that was not their target audience with this camera. It was sports and news.
The 1DX required a balancing act between pixel count and frame speed.
They are very proud of the ISO performance. The English translation says ISO 1,600 is "Beyond Comparison." They talk about ISO 51,200 and even say that ISO 204,800 will work for news photos.
It's pretty clear APS-H is DEAD. The Interview talks about how they determined that the new generation of tele-extenders and lenses perform well enough that they felt comfortable dropping APS-H and that the problem with APS-H was that there is no comparable way to compensate for the crop factor with the existing lens lineup for wide-angle shooting. Seems they figured it was easier to compensate with the telephotos and extenders.
They also seemed to be saying (and as a 7D owner I found this very intriguing) that they are watching the market reaction and may consider a professional 1.6 crop option if the market demands.
Interestingly (in my opinion) is that they make no mention of the "upsampling" idea that Canon first raised when they announced the 1DX. (As an aside, for those wondering why Canon would develop a super-high megapixel APS-H sensor and then drop the format, I believe I read somewhere that it might have been targeted for security cameras. Which makes sense to me. Need those high megapixels to nail your license plate when you run a red light)
They explained their rationale for the double-exposure feature (something I've been scratching my head over) by saying that even though it could be done in an image editing program their research showed their was some merit in being able to view the image immediately in the field.
They talked about raising the total AF performance both with the camera and with the new 300mm and 400mm lenses.
There is a new cleaning system that "burps" the dust off the sensor. (At least that was the translation)
I was fascinated by the pictures of the mock-ups and how much effort went into tweaking the design of the camera to make it as ergonomic and intuitive as possible.
They said they chose to include the LAN option because it is more reliable than wireless and for events like the Olympics and World Cup, the photographers want a wired LAN.
It appears they decided to offer wireless LAN and GPS as an add on because of the difficulty of coming up with a system that would meet worldwide regulatory requirements.
Finally, it ends with some discussion about mirrorless cameras. From what I could tell, it sounds like they feel they are competing very well against mirrorless in Japan, where mirrorless has been popular and adopted more quickly than in other countries. Didn't rule it out, but didn't indicate that Canon has a mirrorless option in the wings.
Anyway, those are my takeaways. Others may have their own interpretations and, of course, if someone can translate from the original Japanese, it would be much better.
