I have noticed this lately in the guide with the 10:00 AM hour of The Today Show. Usually, the upcoming episode is listed as "Today - Kathie Lee and Hoda" (or something like that. I am not actually looking at the guide at the moment, just going from memory.) while the episodes farther out in the guide are simply listed as "Today". Presumably, the title gets corrected when it is closer to the date of each episode, so timers will still work. However, unless NBC is on the bubble about firing Kathie Lee or Hoda (or both) I wonder why the title would not be the same for every weekday episode in that time slot for the entire length of the guide.
Actually - That is exactly what is happening.. I wouldn't think that is the reason for what you are seeing, but in reality there is a change coming.
