Hi there,
So many interesting posts, lots of valid points, but I guess everyone here seemed to miss one of the most important ones.
Fuji got smashed by the competition in one truly indeniable way: lack of megapixels.
I'm a Nikon user myself, so I could easily get into Fuji's system, as it uses the same F mount and D200's body I'm so familiar with.
Love the Fuji's great colors, love the high DR, not so concerned about noise, as my D200 is noisy in it's own way at high ISO.
Price? For working pros, the price tag is not so scary.
So, where exactly did Fuji miss it? Only 6 megapixels, for many generations of DSLRs.
Way too low for a high end, pro, modern DSLR. Waaaay too low.
You see, that's an academic problem. I know how big 6 megapixels print, I know, so don't worry about pointing me out.
I know 6 mp is more than enough for day-to-day use, and will cover 99% of pro needs most of the time.
But, and that's a big but

, it's too low mp for today's standards, when many are already unhappy with FF 12 mp like the D700.
The market (pro photographers, art directors, and sometime even clients) demands higher res than that.
Let's take Sigma's example. Lovely Foven sensor, outstanding colors, and so on.
Many can live with an sluggish camera body, but how can you live with 4.6 mp today?
Sigma's announcement of the 15 mp SD1 caused strides on the market. Why?
It's a 15 mp (!!!!!!) Foveon sensor. From 4.6 to 15 mp? W - O - W
Bottom line: I'd love to buy a Fuji, as long as it was a 10 mp or higher APS sensor.
How about a FF Fuji one? Wow, I'd be the first in line.
So, MP do matter, even when you don't need it.
All the best,
Marcio Napoli
