I am not going to make any claims about who faked the video etc.
But I found this bit of information very interesting while surfing the net about the video.

"On the basis of the picture, his face looks more lined than in the last video, released in October 2004. But thanks to his trimmed and dyed beard,
bin Laden manages to look younger. In his last appearance his flowing beard had turned almost completely grey. This time it is dark black. But the
makeover, possibly evidence of a mid-life crisis for the former millionaire businessman, risks provoking doubts among some of his militant followers,
who normally frown on trimmed beards as a sign of vanity.
Wearing a beard is not obligatory for Muslim men and is only "Sunna" or following the lifestyle of Muhammad.
But some radical Islamic sects, particularly bin Laden's allies in the Taliban movement in Afghanistan, consider it compulsory for adult Muslims.
Clean-shaven men, and those who trim their beards, were often punished for the perceived crime.
Until now bin Laden has left his beard long and uncut. Some conservative Muslims henna their beards, but it is rare to dye them black. "



or maybe he is dead, or underground with hitler and elvis. (joke)
