LP goes, on average, about three years before they release a new studio album. Even if they are in the studio "earlier" than expected that does not necessarily mean they are working on the 7th track of a 12 or 13-song album already. I'd give it about 3/4 of the way into 2012 or somewhere around early to mid 2013 (Summer) for a new album release. Then I'd give it a few more months after that before they start touring again.
Just my two cents.
WHEN LINKIN PARK COME TO BRAZIL AGAIN???????????????????
It's coming out late summer or early fall of 2012 . YEAHHHHHH BOYYYY! :D SO EXCITED.
