This from THR.com:
"I have not met with del Toro. We don't have any near future plan. I don't know if something got misconstrued or miscommunicated but the source was not accurate at all."
He added: "I love Guillermo del Toro and Peter Jackson, and I certainly wouldn't take myself out of the conversation ... if I was part of it. But I haven't read a script or talked to anybody about it."
Latinoreview.com has a bit of retracting to do. Will they do it? No, probably not.
The writing was on the wall in the form of scheduling for this rumor. 'The Hobbit' is scheduled to start filming in May, as 'Spider-Man 4' is scheduled to start filming in March. No can do.
