User blog:General MGD 109/Whats next?

Similiar to previous blog posts, I'm wondering what stories will they adapt for Grimm next season? In season one it was only Fairy tales and a fables, but this season they've included myths, classic literature, poetry and even real live quotes? So what do you think they will bring up next? Granted there are still a lot of fairy tales left to adapte (Snow white, frong prince, Puss in boots) but what else do you think there adapt (loosely)?
