I for one really hope Emma Watson does NOT decided to bow out of the Harry Potter movies. She cannot be reaplaced any easier than Harry could. I understand what she is thinking - she will be around 20 when filming is over - but even at 20 years old she still has her whole life ahead to go to school and start a different career. And with the money she has made from the movies, doing those things would be a breeze. It is bad enough that Richard Harris died and had to be replaced - I think I would rather the studio stop making the movies than watch a different Hermione.
