It will be a totally boring anticlimax, of course.

Rumors and speculation that there are major new findings from the mission at this early stage are incorrect. The news conference will be an update about first use of the rover's full array of analytical instruments to investigate a drift of sandy soil. One class of substances Curiosity is checking for is organic compounds -- carbon-containing chemicals that can be ingredients for life. At this point in the mission, the instruments on the rover have not detected any definitive evidence of Martian organics.

Well that sure is an anticlimax !

Really....They do not, will not, can't, ever, annouce anything that would turn global beliefs on their heads.
Chaos otherwise....

Agreed, to think NASA would tell the truth about anything is a symptom of delusional thinking and should be addressed immediately. Thorazine will help.
