Led Zeppelin, new Studio Album and Comeback Tour in 2016?

There has been some chatter again lately about whether it’s true that Led Zeppelin has a new album in the works and is planning a tour with all surviving members.  Some say sources reveal that the band has several tracks down and have been regularly visiting a locked down/security-posted studio but no one is making an official statement.   The band has been releasing reissues of the catalog this year but no word on new material.  I guess we’ll see if/when something is released.  Fans are still hopeful and continue to spread what news they have on various social media sites.
