Porco Rosso to fly again!

Possibly. Story here.  Quoting Miyazaki:

"So I want to escape to "Porco Rosso: The Last Sortie". I have all its materials." "It should be interesting." "It is set for Spanish Civil War."
"If next two films succeed and Suzuki-san lets me make it (Porco) while saying, 'It cannot be helped because it's a hobby of the old man', I'm happy. It's my hobby."

If you have any interest in planes at all, you owe it to yourself to see this heart-breakingly great movie.
