The saber (and hand) didn't have to fall down the same shafts Luke did. It looks like the massive air currents affect Luke's fall in ESB, so the saber could end up elsewhere and caught on something.

Hmm... I got the idea that all those air shafts end up leading outside.
I suppose it could have caught on something, but the idea of someone finding it seems very unlikely to me. Not sure I can buy into it, but we will see...
I just hope the rumors of the movie opening with Lukes hand still clutching the saber handle and floating through space are false!

The idea is hardly new: in The Last Command, the clone of Luke was grown from the chopped hand, and used Luke's first lightsaber.

Luke's hand was said to be one of the Emperor's prized specimens held at the Wayland facility. Presumably it and the lightsaber were retrieved from Bespin so that Palpatine could make an evil clone version of Luke if he failed to turn the real one to the dark side.

LAME!
