One point worth noting, as far as I can tell all the current research focuses on the surface. We simply don't know if there is water deeper than a few centimeters or feet under the surface.
Multiple missions that should be landing in the near future are looking just into that, in the south polar regions (Shackelton crater & co). So we should hopefully have some new data on this quite soon. :)
