Is lucy,Edmund,Susan,and Petter pevency going to return to narnia?

They all make an appearence in The Lion The Witch and the Wardrobe, and Prince Caspian, Lucy and Edmund go back in The Voyage of The Dawn Treader. They then are told they can't return, but in the last book (The Last Battle) all come back except Susan. The narnia they come back into though is dying and they enter a new one. They come back in the very end of the book.
