I think that there is water ice at the lunar poles; I think there is minable quantities of water at the lunar poles.
I think this because there is various facts which point to this conclusion.
But it is also possible that there is no water at the poles or it's possible that the water which is there, is not enough to be minable.
I'm not very confident of the Lunar Prospector results, I am still hoping that the same instruments used on the Odyssey mission will help clarify these results. Also think that there is a likely similarity between the Moon and Mercury's poles; so even if nothing else happens with Lunar exploration (in near term), and the upcoming Mercurcy missions are successful, this then too might shed more light on whether there is minable water at the lunar poles.
But as far as I'm concerned, the fact of whether or not there is minable water at the lunar poles is [IMO] the most important question we need answered in comparison to all other space exploration. Exploring the Moon to determine if there is minable quantity of water *should be* NASA's top priority. The fact that it's barely on NASA's radar says volumes about NASA and it's inability to do it's job. Sometimes I *feel* that this situation is quite "shocking", but at same time I know, the general lessons from history indicates this to be rather normal behavior. And we will evenually explore the Moon for water and it will probably happen- sort of like "remembering" you haven't eaten & wanting something to eat. Though perhaps, thirsty is more appropriate.
