To me, "we want to see what the actual sales numbers will be for the 1D X and so determine how many customers we might be losing if we do not introduce a higher resolution camera"
says - you ain't seeing a Higher res camera until
a) The 1DX has launched
b) They have analysed the sales numbers
but they also said "and if the projected profitability of a higher resolution 24Ã—36 mm format camera will justify development, marketing, and manufacturing investments"
If it was nearer ready, why would they be talking about development costs?
"or if there is a sustainable market for the even greater costs of development, marketing, and manufacturing medium format cameras and lenses â€“ an area where we have no internal expertise."
Ie - we haven't even started much if any development for a medium format camera, we haven't really done much yet on a higher res camera, and we're waiting out the 1DX launch and feedback.
Putting that to one side - Canon on the intro to the 1DX did say that basically the 1DX was angled more for a niche, and that whilst they had some video options, the trade offs were in order ot make the camera better (eg the ethernet port meant losing some connections useful for video work, I think they mentioned in an interview).
What if they angle the 5D Mark II more to video (through incremental upgrades)? Some side effects will be useful (ISO, grain). Watching a course on making video with the 5D it seems there were needed work arounds for things that Canon could potentially fix, eg
- For your Z-finder - a higher resolution screen would help
- Having an AV jack that could at least take headphones
- Improving Live view (eg the issues of changing output format whilst watching when filming vs playback)
As photographers would like better low light performance, less grain banding, better ISO, better AF, so the video community would presumably want - less rolling shutter, better output connections.
If Canon just bumped the 5D's low light ISO capabilities, and their AF, maybe 3-4 more MP, would people buy? Seems there's a decent enough steady stream of customers.
What'll be more interesting is maybe in a few years time, seeing the low light power of the 5D MkII trickling down to more consumer products.
