Some water vapor might be venting from a couple of craters. You'd have to get really serious about mining to recover any He3 and there is still no commerical use for it.
The "might" could be verified with relatively inexpensive unmanned landers - instead NASA comes up with a multi-billion dollar Moon program, and uses that "might" as a teaser, instead of quickly sending out the probes (it could be done cheaply in less than a year) to check.
