I think another huge thing was the target audience. RR's readers have become older so who wants to see 12 year olds. Also, I think they wanted to shy away from WE ARE THE SECOND HARRY POTTER BOW DOWN because they already had Chris Columbus as the director and showed it during Part 6 or 7 or whatever movie was out at the time.
