Would you buy the 7d with updated technology and an Aps-H sensor. This is the 1.3 x crop and it's only in the pro 1d series, but I would buy a 7d with the larger sensor

7d + Aps-H
14 (18.2%)
7d + Aps-H + 21+ Mp
21 (27.3%)
7d + Aps-H 102,800 ISO
17 (22.1%)
7d + Aps-C + 21 Mp
8 (10.4%)
7d Aps-C + 102,800 ISO
17 (22.1%)

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.
