He could be releasing one short story in between each of The Heroes of Olympus books. I mean for awhile he would release a Kane series book in the spring/summer and a PJ/HoO book right around Fall/Winter. I know Rick always says that he needs a year to right a book, but now he can focus on one series which may give him time to make a few short stories here and there.
