In-body IS is the future, in-lens IS is the past except maybe for extremely long tele lenses.

I remember the days not long ago when everybody was joking about the measly 2 f-stop efficiency of in-body IS. Today the outdated 3 f-stop gain of the Canon 17-55mm IS is the joke really. The spread between in-body IS and in-lens IS will continue to rise simply because it's so much easier to move the sensor in multiple dimensions.

Sure, Fuji has no IBIS but it's inevitable that they'll include it soon. Till then I prefer not to have that useless IS group in the lens that does not contribute to the optical performance at all.

 

Hmmm, let's see if your prediction might happen. I'm a little bit more careful about IBIS: The two Pentax I once had (K-m and K-x) both had that feature and I always suspected this the reason why some lenses were not sharp wide open. One of them was the Tamron 17-50/2.8, even after I sent it in with the body. My explanation was like "if the sensor can move, how's the position defined without IBIS?" Since I know about the field curvature of that lens, I'm not that sure about this theory but after all, who guarantees the correct position if switched OFF?

 

However I found a demonstration from the Olympus sensor shift pretty convincing,
