I don't really have a plan either. Currently using a 5dIII which I am very happy with. I'd like to upgrade, but I'm not sure any of the current bodies have any compelling features for me to justify the upgrade cost at this point. Having said that, I'm not really sure what I would like to see to prompt an upgrade....I suppose just general improvements across the board (MP, noise, AF, etc.). I would like to have an intervalometer built-in (which the 5dIII doesn't have), but that's not enough of a specific need to force an upgrade. My other issue is that I'm not sure I want to hang on to the 5dIII for several more years to possibly wait for a 5dV; I'm not sure my current camera would last that long. So I may be interested in one of the other 5d versions (maybe a new sR?). I looked at the 6dII, but seemed like more of a lateral move from my 5dIII.
