Star Wars: The Early Days
This could be interesting. Besides the obvious cool factor, there might be some early comments regarding the ANH novelization and/or Splinter of the Mind's Eye, though the latter seems less likely given the topic of the fist film.
There's a very outside chance that we may even see an early version of the "Gospel/Gossip" quote, though I'd imagine the timing's too early for any such declarations. (Besides which, it'll be written by a licensing guy based on earlier licensing-guy interviews, so there are limits to what one could expect.)
