Theories about Ghosts in purgatory? I noticed a lot of similarities with Bobby becoming more monster like as a ghost and those episodes where we see people as Vamps (in particular Gordon and Dean). People trying to be normal but give in to their Monster side.

So personally I think Bobby will be in purgatory.

As for Levis, I don't think Dick can get out anymore. The main problem when Castiel took the souls was that Leviathans weren't souls, they were very much alive. Dick, however, is now dead. He can't get out unless resurrected and all the "alive" leviathans are all outside scrambling around like headless chickens.

Season 8 will be about the Words of God. It would fit: Crowley wants more power, too few angels to really stop him AND he has the one person alive who can read the tablets. How Sam will play into that, I'm not sure. He might be looking for a Word that can free beings from purgatory (but I'm not sure WHY God would do that after putting so much effort into putting monsters like Leviathans in there)

Finally Cas and Dean: In the classic biblical mythology, Purgatory isn't exactly eternal. It's kind of transitionary. I feel like there might be a system in place to put the good monsters (the ones who tried to fight their 'curse' or who found ways not to kill people like the Animal-Eating Vamps) into Paradise. Cas and Dean could do that and go to Paradise, rally whatever angels are left, and fight Crowley. And hey, God might promote Cas to Archangel for all his trouble
