This is just my own gut feel, others may not feel the same:
If Fuji were to introduce their own body and lenses, I will definitely consider it more seriously then I do now. The way that things are now, Fuji cameras are just like 2nd cousins to the N bodies. Except for the DR, I have not consider any of their other capabilities. I think Kodak took this route of buying N bodies as well and they too have died.
A good DSLR will need a intelligent sensor with wide DR & low noise, sharp lens, Camera with good feature....etc. Just that Fujifilm are focus on other business. Based on their capabilities, I belief they should be able to develop a camera much better than C & N.
Many photographers whom switched from Film to digital, they are impress on Fujifilm's DR and Color. When they heart Fujifilm DSLR is going to EOL, many of them rush to buy S5Pro.
because they worry... can't get a camera with such DR & color any more.
Nevertheless, I still hope that Fujifilm can Continuous their DSLR.
Dream .....again... ?? Please wake me up....
