ABC News is reporting that:

U.S. and Pakistani officials have narrowed their search for Osama bin Laden to a caravan near the border of southwestern Pakistan...

The CIA and Pakistani Army are electronically tracking the large caravan of people on foot and horseback through the rugged mountain area of Pakistan between the borders with Iran and Afghanistan, Pakistani officials told ABCNEWS.

Osama bin Laden may be traveling with the caravan and may be on foot.

Officials have cast a net around the caravan — using electronic U.S. surveillance and planes with cameras that can see through darkness to monitor its movement along a trail.

This following on the heels that two of his sons may or may not have been captured recently.

I suppose it's difficult not to get caught up in Misinformation Fever. Seems like the rumors are flying hot and heavy, and of course news outlets want to be the first ones to get any kind of scoop on the biggest story.

So I'd take both of these stories with a little grain of salt, though there's nothing wrong with hoping that they're true.
