I saw on the news that the Al-Qaeda have admitted he is dead. I was going out of the house at the time though so I only heard the headlines.
EDIT: Found a link to it: http://www.bbc.co.uk/news/world-south-asia-13317717
Of course there's still the possibility he didn't tell his subordinates or they're pretending but I like to think those chances are quite low. After all, if America had faked it, what would they get from it? Pakistan no longer trusts them properly and it would be easy for the Al-Qaeda to expose them by proving he isn't dead.
