They only site having 30 levels. Either the press release is outdated or the Vignettes will not be included.
Highly advanced artificial intelligence with creatures that actually learn, adjusting their actions based on your tactics. They'll plot, wait and ambush you from all sides.

The lighting in the screenshots looks weird, though.
