I think the inconsistence among different promotional images is normal, because most people won't even notice any change of the castle. We need to wait for the release of the last film to make a conclusion. Maybe Warner Bros will try to make the viaducts in the film consistent during post-production. LeeThree11:15, May 19, 2011 (UTC)
After watching the trailer again, I think the old viaduct is actually removed. Here's a screenshot:
Yeah, it's definitly been removed. Which leads me to wonder, what are Harry and Voldemort jumping off exactly? Everybody keeps saying the Astronomy Tower, but that's clearly not the Tower, and it looks to be in the rough position of the Stone Bridge, but it's too narrow to be that. I guess I won't find out until July 15.Drummerwiz92 14:33, May 19, 2011 (UTC)
They're jumping from this building, the new entrance of The Quad
