Zap2it is going absolutely crazy with these episode listings. Four more episodes have titles, and the newest two are probably planned for Season 5.

The new episodes include:

Stuck Together
The Trial
Off Colors
Lars’ Head

While Zap2it is a reliable source, don’t take those air dates to heart. We have absolutely no idea when they’ll REALLY air, but it’s good to know that Season 5 is being worked on right now!
