Water or lack of on the moon

Does anyone have predictions about the results of the LCROSS experiment?

I think there is some water in those southern dark craters. But if the rocket stage had hit a serious ice deposit NASA
would have announced preliminary results within a few hours.

So I see two possibilities.
1- The rocket stage hit a bedrock outcrop. Would this explain the small amount of material ejected?
2- There is some ice but it is in very small quantities.


Any thoughts?
