What to do? What to do?

...One thing I was wondering about was if the 40-150 would be too much zoom for animals that might get close to the jeep. Would I miss shots in the time it would take to change to the 12-40?

I guess that would depend on the size of any such animals, right? Of course you might miss shots by having to change lenses if any such shots materialized. I've seen photos of elephant menacing safari vehicles. My son was on safari in Tanzania and someone opened a window to take a photo when in a flash a baboon jumped in and stole someone's pack. So, there might be shots of nearby things.

...So right now, I am back to being inclined to go with what I have i.e. Oly 12-40 2.8; Oly 40-150 2.8 + 1.4TC ; PL 100-400.

What is the rationale for the 40-150? One body with the 12-40 would cover typical travel stuff (it won't ONLY be about wildlife), all but the most panoramic landscape shots (stitch the exceptions), village/camp shots, candids, or animals near the vehicle; the other body with the 100-400 should cover most of the wildlife, and you would almost never have to miss a shot or get dirt in the camera by changing lenses.

Some shots you will miss no matter what kit you carry...too dark, too slow, too close, too far, too lazy, wrong settings, etc. Get the ones you can without becoming a walking gear warehouse and don't ruminate about the ones that got away.
