Watched his last keynote address at some oculus event and it was disappointing enough that I won't bother with the next one. He used to cover a ton of topics but now they've put a stringent time limit on him and don't allow questions or provide him with a whiteboard. Most of it was about customer experience in VR and a few experiments he did in that area.
Facebook being able to screw up what was a sure thing that's as easy as giving a man a room at a conference hall for an entire day to talk about what he wants at the pace he wants shouldn't surprise anybody.
