I don't know about early leaking, but certainly John Solomon's AP article yesterday was mostly comprised of pro-Rove information.
This NYTimes article is puzzling. It starts out by saying Rove and Libby may be targets, but also says Fitzpatrick hasn't made up his mind about bringing charges. On second read, the article is less certain than first glance leads you to think
Earlier in the investigation, Fritz said Rove was not a target. Other than that, he's said nothing to anyone. I think the press is just praying to their Gods right now, hoping to create an illusion of reality.
I'm not going to freak unless something bad actually happens.
