Batman and Detective are obviously safe.
Harley will probably be relaunched.
A Batgirls book is quite probable.

The rest is up in the air. Quite frankly, if I were at DC I'd push for the rest of the Batfamily having each an OGN per semester/trimester. Kind of like :

Nightwing -> [Batwoman? ->]Red Hood -> Red Robin/Robin -> Damian -> The Signal [-> Batwoman?]
