I think Kreacher might play a BIG roll in the last book (spoiler on the movie??)

I'm only saying this because I saw the 12:01 showing of OoTP this
morning and it made me think. I heard rumblings that the director had
wanted to get rid of a character during the 5th movie but JKR said
they could feel free, but they would have a big problem come the 7th
movie.

Now, after watching the movie I think that character might be
Kreacher. He was in the 5th movie but his roll was SO small that it
makes me feel it was added in hindsight, or just to say, "ok, yes this
character exists." but that seems about it. 

Has anyone else who's seen the movie gotten this feeling too?
