A recent article in PC Mag points out that most film these days winds up, at some point, in digital format. It is simply a lot cheaper, a lot faster, and offers a lot more capability to work with digital images. That doesn't say that film is out yet. However, its claimed advantages are lost when it is converted to a digital form. Many are beginning to capture their images in a digital format.
That, of course, does not mean that the film 'look' is dead. That remains to be seen. If memory serves me correctly, the Canon HD camera has a 24p option. I don't recall if the Sony camera has this.
Someone investing for the future should clearly be looking to HD. SD is today's technology, and is likely to fade rapidly.
