I don't believe so and continue to offer them. What I am looking for in this thread is a discussion on what the best possible virtual tour would be. What you like, what you don't like and try to look at the presentation as if you where a real estate buyer and if you where an agent that I need to impress.
Here are two that I have done recently. It's a high end home, but I also do the bread and butter homes as well.
