WDYTYA – postponed again?

The running joke keeps going. The US version of Who Do You Think You Are? when last heard from was supposedly slated to begin in January 2010. I just looked at the NBC schedule beginning in January and WDYTYA is not on the schedule. Another clue is the WDYTYA; companion book by Megan Smoleyak was originally coming out at the end of December. Now the release date on Amazon.com shows as March 18th. NBC has the Olympics on in February. March seems much more likely for a start date for WDYTYA.
