Congrats. Can't wait to see your impressions.

Most of what I've seen so far is pretty encouraging. I mean, of course some people are jumping on initial results (some of which seem very dubious)and crying foul, but overall the 5DIV seems like exactly what I would expect from Canon, a well done, worth update to an already exceptionally popular camera. The early pictures I have seen are fabulous and even the early test charts at high ISO are encouraging that there might be a 1/3 - 1/2 stop improvement in noise even at high ISO. I've yet to see the 4-5 stop torture test that people seem to think should be a new standard.

But, in terms of early data, this is by far the thing that has caught my eye the most:

Basically, the dual pixel technology, one row is under exposing by 1 stop. Also, they are observing that the entire 14 bit histogram is being used filled by both pixel row readouts and, for the first time, the full 16,383 (their number---14 bit--2¹⁴ = 16,384) readout potential is being used.

For years, I have heard people lament that 14 bit was a misnomer as the entire range was not being used in the actual readouts. Apparently, with the 5DIV, this may have changed and not only do we have full 14 bit readout, but, with two pixel rows offset by a stop, the potential for 15 bit range of data. Or, to quote the article directly "the dual-pixel raw file for this camera contains 15 bits of raw data, if you consider main and auxiliary subframes together."

Perhaps this will not lead to much, but it definitely has my attention.
