You know I sometime wonder, too. In my case, it's complete stupidity. The only two things in the world I am allergic to are photo chemicals (I think fix) and latex. It affects only my hands and it is very uncomfortable. And yet...
After shooting digital for a living for several years, now that I am doing something else, I am exclusively working with B&W film and I like it. I don't care that digital is sharper, that it captures more detail, that is flexible and superior in low light... I just like the way wet prints look and feel. I don't begrudge people their expensive digital cameras. I admire work people do with digital gear. But for me, film still holds magic. It's just that simple. I like what I get with film.
As for all these announcements, none of it gets me excited. Maybe because there is so much of it that I can't possibly pay attention to it all. My D200s are on their last legs. They have helped me make a living, but I never really enjoyed working with them. I am probably going to get something pocketable like Fuji x10 so I can post photos to facebook and email the pictures of their grandkids to my parents. For my documentary work, film is good enough and I have plenty to learn about it.
Sometime ago, there was a thread about somebody saying they will do something else if film disappears. I kind of get that, actually. Over the past year, I have been taking some drawing classes and practicing sketching. I am not saying I plan to abandon photography all together if film becomes unavailable, but there are tactile, slow aspects of film photography that are important to me and digital can't really replace it.
