Matt seems to be well liked inside NBC News, this is probably one of the reasons why they halted the planned reboot last year -- he was strongly against it and the right people listened to his wishes (it pays to have friends in the right places). I feel like you're right about NBC News, they are in the midst of rebooting MSNBC right now and I doubt that are actually thinking about replacing Matt on the Today show, which isn't doing that bad anyways. They probably believe that they have some momentum to fully overtake GMA, which is debatable. I'm not really a fan the current state of GMA (which has become a QVC, MTV's TRL, Inside Edition and Entertainment Tonight all-in-one) but I still marvel how they are still on top, I think there's a perceived notion that GMA's cast has better chemistry than Today's. Personally, I don't think Matt ever fully recovered from the awkward Ann Curry incident, which pretty much hurt his public persona, there needs to a an eventual shake-up, but it's not happening anytime soon.
