I've been downloading some crime podcasts and I've just seen that Authors on Tour have recent podcasts for Julie Kagawa talking about The Iron Knight and Gena Showalter about Twisted. The podcasts are only 4 minutes long and were recorded at BEA.
I haven't listened to them yet and I'm so far behind in each series it may be a while before I do for fear of spoilers.
You can listen to Julie Kagawa here and Gena Showalter here.
Alternatively you can subscribe via iTunes (search for Author on Tour).
