The 7d with an aps-h sensor!!!!!!!!

[Kuscali]

Olympus has an acceptable swivel screen, something akin would work for a7DII/5DIII.

Ad APS-H, mirrors and LV: how about dropping the rigid EF/EF-s seperation? Give the mirror also a powerless resting MLU-mode that retracts a locking pin that would prevent bad matching between modes and lenses. For the viewfinder a beam splitter that merges/switches between the images from the mirror and a display would be an option that also opens a door for lots of other uses. Or simply use just the rear display as a screen for EF-s lenses. With the 10-22 it wouldn't hurt and with the standard zooms we're at least close.
Bonus points for merging the AF sensors into the imaging sensor, thus allowing PDAF in LV and movie modes.

Can you explain what you mean by dropping the rigid EF/EF-S separation? If a 7D mark II comes out with a APS-H sensor there would be two major problems with Ef-S lenses on it.

1). The mirror is too big, the EF-S lenses have parts that go to far back in the body.
2). Some Ef-S lenses already vignette on APS-C sensors let alone anything bigger.

Yes, the mirror is to big, thats why an EF-s lens could only be attached while the mirror is locked in the "up"-position. The camera would work like an EVIL.
Vignetting wouldn't be that much of a issue as the camera knows the true image circle at a given focal length. You read only the part of the sensor thats actually illuminated. You don't get the full resolution of the APS-H sensor if your at the wide end of lens, but an indicator in the viewfinder could tell you to zoom in a bit for best results.
Similar to the masking the FF Nikons do, but in a more sophisticated way.

Interesting about mirror having to stay up.  Canon did submit those patents for overlaying an LCD image right into the viewfinder.

EF-S lens will not work right with APS-H sensor due the the image circle of the EF-S lens  is not large enough for the APS-H sensor.

As mentioned above: you don't need to read the whole sensor, just the parts illuminated.
