What sort of world do you think we're getting with the Game Pack?

I am hoping for a large new world with this pack as the world will be the major selling point for me.
Scottish Highlands would be great. I love the idea of cool foggy mornings so I hope you all are correct about the fog.
Whatever it is I hope it has large lots and swimmable water.
I also had the thought of London, there was a movie called "American Werewolf in London" and then the short in the announcement trailer looked like it could have been in a city.
