It really depends on what/how you shoot. For instance, with the A7r2, you have iso 100,000 (400K+ with the A7s). So fast glass for low light becomes a non issue. Now DOF is something else, but with full frame and shooting f1.2, your area of focus is pretty razor-thin and frankly not particularly useful other than for effect.
If these are MF lenses then you'll want focus peaking to help with focus as well as zooming (which is easy with an EVF). Frankly optical viewfinders are pretty much dead as well - the new Leica EVF is 3.6 million dot resolution.
The bottom line is that the SLR has little future. Only ones that really need it are sports shooters (it still has a slightly quicker AF) but frankly they can shoot 4K video with a mirrorless and do a frame grab that will be plenty good for most publication. Mirrorless is only going to get better. So do you invest in something that is near the EOL, or something that is on the development curve?
Right now it is hard to beat Sony body and Zeiss glass. The new Batis lenses are spectacular. While you invest in the glass, there are sea changes that can alter the landscape. Mirrorless has been knocking on the door for some time, seems like someone finally answered the knock. If you really love the way your legacy glass renders you can adapt it. Or you can sell the glass to someone who still is keeping that flame and move to current generation AF, etc.
Two years ago I had a different view. But the tech has changed the game again...
