On my local PBS startion they had a preview of some of the new shows/episodes.
What caught my interest:
They only showed one NOVA, on string theory
Warrior Queen http://www.pbs.org/previews/EMMTWarriorQueen/
Drive across the US http://www.pbs.org/previews/HoratiosDrive/
A Nature episode on whooping cranes and teaching them to migrate. Since they started out in Necedah, WI (not far from me) I’m extra interested
Kinda bummed they only previewed one NOVA
