If these things are critical to you and they are not offered on the hardware you choose to buy you have to think long and hard about continuing to buy into that hardware system.
For better or worse Canon has a method of hardware line segmentation that is their own and while they are changing (slowly) they are still more likely not to give you all the feature on all their systems then a lot of the competition. At this point you should know this is how Canon does business and continuing to buy their hardware tells them that you are ok with it (even if you are not).
If my Canon hardware ever fails to meet my needs I will sell it and switch to the company that does. I have not needed a Cinema Camera yet but if I did tomorrow it would be the C70 because I have a ton of RF glass and it appears to record video.
My needs would be:
- fits my glass and
- records video

So far my Canon brand loyalty has been rewarded with Cameras, Lens and features that I want\need so I remain a loyal customer (oh and CPS is awesome).
