Pat, I see this body as being limited use (acceptable use anyway) just as the 7D II is.
It will be a specialty tool that either fits your specialty or handicaps you if you try to use it as a general body.

You will not be able to go as high with the ISO because of noise. Sunsets and Sunrise it will be fine on a tripod. At night at the local club or play it will be weak. If you need higher ISO's it will not be the camera for you. During the day for still wildlife it will be fine, but your day will end a bit sooner and start a bit later because of loss of light. None of these are issues with me since I have multiple bodies and one of the others will perform better in those situations.

One thing I hope to see;

In crop mode it would be nice if at 1.3x the body could do 7 or 8 fps. It would make it a bit more versatile.
