I never read any of the books but curiosity drove me to look at the last page while I was in stop n shop earlier today.

Warning, Spoiler:
Being that the ending fast forwards 19 years to a scene between Harry and his son, I assume that:

a) He lives and

b) The door is open to future books.

Am I right?
