week at that level before it goes to level 90

I just went back to verify this further to make sure I wasn't giving incorrect information. (Sorry for the wow po confusion folks.) There is also an item level that goes with it. At level 85 Theramore's Fall is set to item level 353. At level 90 the item level is currently set for 425.

If you're not at the correct item level for the level 85 scenario when it goes live, you still have some time before it releases (Sept. 18) and it will be running for a week at that level before it goes to level 90.
