Of course the DSLR will increase in popularity that is a fairly safe assumption. There is however, a novelty effect to digital photography to a generation that was used to film. There are those that don't participate here that just want a picture for memory. For many, a paper picture is just fine. They are told to go digital and their worries are over. For many in this generation computer literacy was not a priority.
To assume that film will die or even on its death bed is premature. I still shoot regularly with medium format cameras. It depends on what the final use of shot will be. I do not have the business to lay down the money it would take to have a medium format digital. I think that allot of established photographers are in the same boat. As the digital technology progresses the prices of these should come down and be more attainable to the masses. Imo, we are still a long way from that happening.
I'll use one of my sisters as an example. She was more than happy with her point and shoot film camera. I tried hard to convince her to go digital and her resistance was consistent. Not that she was afraid of learning something new, she just didn't want to have to spend the computer time. I finally got fed up and gave her a Canon P&S for Christmas a few years. She does use it but primarily for those moments when she wants to be able to email a picture to someone. She still uses her film body quite regularly which drives me crazy. There has to be more than one silly sister in the world.
The cameras are becoming feature laden pieces of complexities. For those of us that love photography this is probably good thing. For those that just want a picture of the kids, do they care about most of these things. I would guess that a very high percentage of the digital owners (including allot of DSLR users) just put the thing on full auto and shoot away. Heck, I finally met someone that actually uses the direct print button to a small 4x6 sized printer. At the end of the day they just wanted those prints again.
I think the majority of the answers here will be that film is close to death. I think that it has a presence in the market place quite some time to come. To the masses, I don't think that they care one way or the other. They just want that picture. If you did a national poll I think the answer we got from it would be vastly different from that which we will see here. Photography is just not that big of an issue in most people lives. Even for those that do invest in a DSLR it is more of having the latest and greatest than it is about living photography, which many of us on here do. I think that you would be surprised at the percentage of people that buy a DSLR and them participate in an active forum such as this one. I'm betting it would be less than 2 percent.
For film to be officially dead,imo, it has to stop all production. There will always be those high end photographers that are shooting 4X5 or larger sheet film. We aren't going to see a sensor of this size in long long time. For the consumer market, the film camera is slowing dramatically. As the future generations come along in time to the point where they enjoy the buying power there will be more digitals sold as these generations will be more computer proficient. While the consumer market will be one of the more significant driving forces on where the photographic industry evolves to, specialty film requirements will probably continue to live. I will be long dead and gone by the time we can bury the last film cannister.
