Is that big Orc army we see marching through Dol Guldur going to be present when the White Council shows up? Or is the army headed towards Erebor, leaving Dol Guldur rather defenseless when the White Council does show up to spring Gandalf?

When will Beorn decide to jump into the fray and how many dead orcs does he leave in his wake?
