Yeah, but it was released around the same time as the last book and probably benefited from all that hype that was built up. I'm just not convinced people care as much anymore about the saga since we all know how it ends. Look I'm not saying it won't make a ton of money...just call me a skeptic.
I actually don't know how it ends since I've avoided finding out since I don't have the time to read them (and don't you DARE ruin it for me).
I guess I understand what you're saying, but I still think HP6 will easily clear $275 million. You could have made the same argument that people knew how LOTR or the SW prequels ended and all those movies weren't affected by that fact.
