Well, for the same reason I prefer unibody laptops, I'd prefer the E-M1.

If you want to wait for 4 years of usage so you can assess which is more durable, then be my guest.

Your right to do so, but you might be paying extra money for nothing, or even less than nothing. Typically, you'd put these things through accelerated wear tests, using shakers and drop hammers, environmental chambers and the like. You can simulate the culminated effects of years of use in just a few weeks. I'm surprised that none of the test sites have made any serious attempt to test fro robustness, weather sealing and the like.

We can do two things.

We can observe that the E-M1 is built in a similar fashion to other high end cameras, such as the D800/D4/1D, with a full metal body, and a lens mount attached (or actually a part of) that body.

We could observe that, but we'd be wrong if we did, The structure of the E-M1 is completely different to a SLR like the D800/D4/1D, which are built around a mirror box, which is the structural chassis holding it all together with non structural skins applied to the outside. The key thing really is what locates the lens mount in relation to the sensor. In the E-M1 this is a metal casting just as it is in the A7 and A7r.

We can observe that the A7/A7r is built more along the lines of a 6D (or if you prefer you can propose others).

Not really, the chassis of the 6D (also the 7D and 5D Mk III) is plastic with steel reinforcement.

We can then look at other cameras built using similar methodologies in the past to see how they held up and use that to predict the long term results.

You can't really compare the structure of a mirrorless with a DSLR. The mirror box doesn't exist in a mirror less, thus the design is much simpler and straightforward. In any case, there is no direct evidence that metal results in a more robust construction than plastic.

As you have a lot of experience with this type of thing, perhaps you'd like to proceed.

Also, the E-M1 gets regularly dunked during reviews, so it's not totally being ignored.

'Dunking' is not a particularly severe test. The internal pressure of an immersed enclosure and the surface tension of the water will usually stop much getting in a reasonably well fitting enclosure. Fine mist and high humidity is much worse, generally. Moisture is an interesting one. Most marine instruments are not sealed, because it is almost impossible to stop moisture getting in. To do so would mean hermetically sealing it, but that's expensive and probably impossible for an interchangeable lens camera. If it's not hermetically sealed, it will 'breath' that is take in and expel air as the temperature changes, and that air carries moisture, which you need to allow to get out, so there'll almost always be a drain hole somewhere. The trick of weather proofing is to make it hard for liquid water to enter through any of the routes that it will probably come, and labyrinth seals can work just fine for that.
