FujiFilm Japan has released the first official sample from the HS-20 EXR.

I downloaded it and ran it through my normal editing routine. A little contrast and colour adjustment and a small amount of sharpening.

Keep in mind that this is shot at base ISO and also without any of the EXR sensor DR adjustments applied.
