Looking at the village below, I thought it looked more European - possibly Gallic - rather than English. Maybe they're heading to Beauxbaton, or possibly to where the giants are. Or maybe they're just laying waste to New Zealand because the Lord of the Rings films are better than theirs, and they left out Smaug.
I'm with you, SPF; I want Harry to go back too. And I'd like to Norbert.
I don't know what I think about the fact that Harry is there with Ron and Hermione. I was thinking about the climaxes this morning: in the PS, it is the 3 of them until the final confrontation. In CoS, Ron comes as far as he can. In PoA, it's Hermione. In GoF, it is Harry very alone, and he fails to defeat Voldemort for the first time. In OotP, it is all his chums, and the Order. In HBP, he's with Dumbledore.
I thought that this one would have him alone - but then again, we don't know where this is in the story.
There's no sign of swords or armour, which I thought might come into it. Harry appears to be wearing a dragon-skin coat, with the other two in their uniform. Maybe Harry cruises up on his dragon, hangs around out the front of the dchool, smoking, and takes them for a spin on his dragon.
