Michael Hirst has said that he will not be carrying "The Tudors" on into Edward, Mary and Elizabeth's reigns as Edward and Mary's were relatively short and he has already done Elizabeth (the two Cate Blanchett films). In writing "The Tudors" the way he did, he actually cut out a few vital characters - Lady Jane Grey, Mary Queen of Scots, James VI for starters - so it would be tricky to do anyway.
