Doctor Who Series 4 Preview

I was mucking around on the internet the other day, looking for more Doctor Who news. I even went to the Sci-Fi channel’s web site hoping to find out when/if Series 4 will be showing in the United States. Turns out Series 4 will be showing here on the Sci-Fi channel, but that haven’t announced when it will be on. In the meantime, someone on the message boards posted a link to a Doctor Who Series 4 Preview on YouTube. I post it here for those of you who have not yet seen it.
