From the YouTube description:
An introduction trailer shown at the 2007 International Comic-con in San Diego, CA. This video was only shown to about 4,000 people. The producers plan to release the 16 new episodes by spliting up 4 full-length DVDs that will be released both on DVD and shown on Comedy Central.
It’s great to see Futurama returning to our screens in 2008, but 16 episodes is a little bit less than a full season. I certainly hope the DVDs will sell so well that Futurama can finally pull a Family Guy and return for many years.
