The page captured a tweet from musician Chris Jericho, which apparently leaked the release date of an album. Jericho's post featured the band's logo and the hashtags "Voltaic Oceans" and "December 9th," which could refer to the title and release date of the new work. Jericho deleted the tweet after a few minutes.
According to the news site Blabbermouth, details of the new album will be released on the 27th. The band has only posted a new photo on their official Facebook page, showing the members with their faces crossed out (above).
