Four new episode titles for Supernatural have been revealed, read them here!

SpoilerTV reports:

7×16 ‘Out With The Old’ (March 9)
7×17 ‘The Born-Again Identity’ (March 16)
7×18 ‘Party On, Garth’
7×19 ‘Of Grave Importance’

At least we can surmise from this that D.J. Qualls will most likely be appearing in episode 7×18! The title of the episode before this, ‘The Born-Again Identity’, may refer to Castiel, as Misha Collins is scheduled to return around this time (not necessarily in this episode however).
