For me, I've been waiting to get into video, and finally had the right excuse - a project that will really be ideal for the video format. I ended up buying my video camera just a couple months before Nikon came out with a still camera that does video - though I don't think that their or Canon's option would have worked for me.
I think that as we move along, not only video, but other areas of multimedia will be important for photographers to have at least a basic understanding of. Photos simply aren't worth enough any more - we have to find ways to increase the value of them by incorporating them into the final product and selling that - albeit a video, a website, or a book. Video is just one of the tools out there to allow us to use our most important asset - out artistic vision - and come out with a different product for a different market.
