It was decided that we'd like to polish things up a bit more before officially showing the world off (the blocky cliffs are my personal demon to vanquish, but I know everyone on the team has their polish points they want to get in before lifting the veil).
How about my personal arch nemesis: bloom? 
PS. the video is still available though. 
Edit: Imo though, no reason to hide it. The new graphics look quite well. Especially the fallen territory.
