For all you people who want a review of the train, I just got it, but I'm saving it for this four day weekend, so I'll post some pics when I open it, if a review doesn't pop up before then.
And the great hall size is correct in correspondence with the clock tower, the astronomy tower, however is not. You should trust me, I know everything about Harry Potter.
And, @Big Brick, I feel that the first castle was pretty good, except the roof. The third one is ugly, but is forgiven for Hogwarts MOC potential and figures.
I only need Hogwarts castle and Hagrid's hut now, but i don't know if I'll get Hagrid's.
And the Lego group probably is waiting for the release of the seventh movie to promote these sets. I wonder why they won't release the Diagon Alley at christmas, It'd be right after the new movie, so hype would be up, and then a huge holiday that people tend to buy gifts at, it just seems stupid.
Is that it? Yeah that's it.
