I was shooting video 10 years ago with my home builders and creating CDs laser-cut in the shape of a house. The CD contained image slideshows as well. After 10 years, the only thing that has changed in video is that you can stream over the internet better. Video and Dial-Up never did too well together back in the day. :)
While I like video you still can't manually look around in it. You can't zoom into it or create hotspots (unless you have some flash skills) :)
I'm still doing pretty well with virtual tours but I bank most of my business on a combination of items like web design, photography, interactive components and video.
To me...the important thing is not putting all your eggs in one basket. Offering many different types of services to your clients gives them lots of choices and plenty of steady work for me.
