The XPro-1 isn't going to replace my Canon gear in my studio any more than my Hasselblad gear has replaced my Canon gear. The right tool for the job and all that. But if I wanted to add a carry around system more for my personal enjoyment and as a back-up, it would be great.
However, it is so tempting to think what Fuji might do with a larger sensor given that Fuji has experience making medium format bodies and lenses. If they made a medium format sensor with their new sensor array and added a medium format body and their Hassie lenses for a price between high end dlsr and lower end mfd, it could take over the market. With their experience, it wouldn't be very hard. Of course, they may not feel there's enough market to do that.
But even if they come out with a full size dslr sensor it would probably out perform any Canon or Nikon out there, D800 included, and if it did that it would really be in mfd territory performance wise. I know I'd be selling all my Canon equipment and my H3D2-39 and four lenses.
