There is always that chance that maybe an APS-H 10fps 7DII with EF-s compatability is coming. I think it would be a fantastic idea If it plays out.
I think this is physically impossible. The image circle of a EF-s lens is too small to 'expose' the whole APS-H sensor.
A crop mode like Nikon?
Makes sense, buy (and pay)an APS-H senosr, and then run it in a crop mode...
The other problem is the mirror. EF-S lenses use the space that was freed by the smaller mirror for APS-C. I think there also would not be enough space for an APS-H mirror. But, you are free to use third-party APS-C lenses (Sigma, Tamron) even on a FF Canon Body, and crop it on your own.
If they could do it right as not to alienate current efs lens owners and give the extra reach/IQ when using FF glass. I'd buy one.
