Unless you do video, connect the camera wirelessly, or shoot at very high ISO's, you'll likely see little benefit going with the latest and greatest full-frame Canon. I'd get a very clean, last-generation Canon Mk 5 and shoot it until it quits, which should be quite awhile.
Remember: you only "date" the camera body. You marry your lenses. Save money on the body and put it toward good glass.
