He's going to end the show with a "Few thoughts on a new era". I won't be able to transcribe real time, but I'll provide a gist after I hear it, perhaps there may be a transcript of the news later. :)
In the end: He launches praise and accolades for all the hard work Brokaw did in the 20+ years at the national anchor desk he now sits behind, hard work that puts him at the top at the beginning of his tenure and he said he will work hard and make sure the news department that worked under Tom works as hard as they have for the past 20+ years to keep NBC News on top. He even said that he felt humbled to sit in for Tom during Tom's many absences for vacations or on-assignment reports. Of course, he said Tom isn't going anywhere, and we as viewers shouldn't either(I have to admit, I laughed at that of course).
