May I have a few opinions from Harry Potter fans?

[Loki]

A) Do you think there will be a Harry Potter Broadway show soon?
B) Do you expect Potter to become a TV series? ...If so...Live action or animated?
C) Will Rowlings write more books of magic?...If so...will they be about Harry or someone else?
D) Will Rowlings allow others to publish books about the magic universe she created?

Just a few idle thoughts I had while waiting for the final movies.
