WorldThreats.com, which seems to be pretty reliable on these matters
is saying this:
Conclusion
The conclusion WorldThreats.com has reached is that either Osama Bin Laden is in custody (alive or dead), OR we have a general idea of where he is, and we will likely nab him within six to eight months. If he is in custody, this will be announced either when Zawahiri is caught, or when all actionable intelligence from his capture is used up (which will take a bit of time). If Osama is caught, and held, and the US decides to “pick” a place where to “find” him, WorldThreats.com believes that the most likely scenario would be to say he was on the Afghan side of the Pakistani border. This would be the best approach, as saying he was in Iran would create major foreign policy problems, while saying he was in Pakistan could likely result in an uprising against Musharraf. For this reason, it is most likely he will have been said to be in Afghanistan. Already, if the theory about him being captured awhile ago is true, then we may see signs of the stage being set. Recently it was leaked, almost certainly intentionally; to the major media that there were signs Osama was moving into Afghanistan very soon.
Now, you may ask, why did WorldThreats.com issue this report now? On March 8, 2004, the Northeast Intelligence Network was told by one of the inside sources that the announcement of Osama Bin Laden’s capture or suspected death will be made within 15 to 20 days by the head of Task Force 121, Admiral Bill McRaven. “It could be sooner or it could be later, but not much later”, the intelligence source said.
UPDATE 3.14.4: Two high-ranking sources have claimed that OBL will be announced found dead in Afghanistan from "ill health".
I think we're moving toward the endgame right now. If there's an October surprise, it'll be something else. Bush needs to shut down the terrorism fight screw up talk asap. Catching bin Laden that late in the game will cause him too much bleeding among his marginal support. This will stop that "Bush as screw-up" talk and let them move to a more palatable agenda--stopping gay marriage and sports steroid abuse...
