Although I have never bitten the bullet on the new line of FujiFilms, primarily because I have been for many years now assembling my ultimate Nikon DSLR kit which is neither cheap nor a short term undertaking, Aside from building my Nikon kit, I am most intrigued by the work that FujiFilm is doing. They have never shied from being different on the bayer pattern side of things. If I won the lotto I would jump on a camera and their three prime lens kit, plus I see they've got an ultrawide and standard zoom with decent specs coming.
DigLloyd has done some in depth analysis of their sensor output. It appears to be a remarkable performance, which after all is delivering near FX ISO, colour, tonality and great resolution performance in a DX sized sensor. Definitely punching above it's weight although with some RAW conversion challenges. http://diglloyd.com
