Since we are now spitting out random ideas ^(That could be cool) Is it appropriate to assume that the new area infront of Hogsmead arch and the path leading up to the new trainstation will be themed like Forbiden Forest? I think it would be so dramatic and amazaing to walk down a small shaded path from Lost Continent through dense trees that open up randomly to the Hogsmead arch! Also this would be a great way to hid Sinbad (I may have this idea in my head because of previous posts and clues from HateToFLy)but who knows! I love what I see in my head.
I vaguely remember HTF hinting the area between Hosmeade Station and the entrance arch would be getting lots and lots of trees, so I think you are right.
And yes, I agree; the addition of a forested transition is going to make the whole land that much more epic.
