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,

 

I'm afraid that we can already see what will happen - the combination of IBIS and ILIS.

But with IBIS in place there's at least less pressure on the manufacturers to use ILIS.
