According to Koreaboo, Super Junior's Leeteuk has officially confirmed that Super Junior will be staging a comeback soon and in fact, they're already in the preparation stages! It's been quite a while since the last time the group has released an album, 18 months to be exact. Their last album was "Devil" and it was released back in July 2015. The reason for their abrupt hiatus is because several of their members began each of their own military services, leaving only about 4 members active. Now, Super Junior has 7 members active while three are set to be discharged from their military service this year which gives them the opportunity to stage a comeback especially for the fans that had missed them greatly.
A comeback from Super Junior this 2017 also provides Kyuhyun the last time to perform and promote with his fellow members before he begins his own military service.
