Not like we will be seeing then in any more HP books at this rate they are making them. Rupert is in danger of being to old, Dan, I still don't know how old he is, but he can't be fair behind Rupert. Emma seems set because she is 15 and they are doing the fifth book now.
I still liked the third movie because it shows how much Harry is growing up and how darker his life is getting through the books. The first two seemed too happy for me, it is about time they started showing how dark the books are getting.
