Uhhh... have you tried this? When you go to that Apple page, it's covered with photos and ads of the new products they've unveiled. Maybe if they provided a direct video link...
UPDATE: OMG, rainbows of white, you were 100% accurate! I must have been confusing this direct media link with the front page. The apple events link really IS spoiler free! Thank you so much for the link, and I apologize for my error.
