According to this article from Billboard Magazine they're filming a special concert with The Dukes Of September (Donald Fagen, Michael McDonald and Boz Scaggs) tonight at the David H. Koch Theater at Lincoln Center in New York for a PBS pledge drive and a future DVD release.
The PBS taping was mentioned in this article a month ago, where Donald Fagen was quoted as saying that Steely Dan will likely tour again in 2013.
New information in the Billboard article above is that The Dukes Of September will do a tour starting in late 2013 and continue into 2014.
