provided that the new 7D2's high ISO performance would be the same than the 5D3's (which is not impossible but not likely),


Actually, if my understanding of the physics of it is correct, that is impossible. The latest generation of camera sensors are very close to the limit in terms of quantum efficiency, so not much more further to go in terms of high-iso signal-to-noise ratio (though they should still be able to do much on high-iso dynamic range). This means that, no matter how much better APS-C sensors get, they'll never bridge the gap to current full-35mm-format sensors.
