Although I still think that I am right about the main points of my post, I should have been clearer about that. First, I have not written that they did not cooperate, I wrote that they should have cooperated better. This is one of the most important negatives mentioned in the reviews I have read (for example, Thom Hogan mentions that in
his review). I cannot know how much they cooperated and I don't know how much Adobe and others were interested. Implementing the support of Fuji's new sensor design means, that the converter has to be able to cope with Fuji's 6x6 array instead of the usual 2x2 array. Since this essentially means writing a new converter in order to get the most out of the sensor, implementing the support of the Fuji sensors is rather costly. I cannot know exactly whose fault the long delay is, and I surely didn't write carefully enough, but I still think that it would have been very much better for Fuji, if their cameras were supported much earlier and as well as by Lightroom 4.4.
