Watched the demo. Didn't see anything conclusive or that couldn't be attributed to preparation, map knowledge, choke-point knowledge, voice_enable 0, use of radar via teammates view. He was peeking and listened for footsteps/shots. This guys was just trying really hard in this demo. Even with wireframes on, there are times where if he did toggle off, he should have previous knowledge of an enemy and didn't even react to them.
