The Backstreet Boys plan to head into the studio in the spring of 2009 to begin work on their next album, after they finish the Unbreakable World Tour, with plans to hopefully release the album sometime next year, early 2010 [2]. In between that time AJ Mclean announced on 19th March 2008 that he's finished recording and will release his first solo material some time in 2008.
