they're behind on a few different storylines, as merc said, if they even do them.

some that come to mind:

Spoiler	+
-anything greyjoy -the adventures of davos (feat. lord manderly) -where they're at with arya is at the end of AFFC, not ADWD... kinda -something else happens in mereen that we haven't seen yet

that's all i can think of off the top of my head
