According to various news articles, Super Junior is in the midst of preparing a meaningful album to commemorate their 10th anniversary. It will not be a regular album but an album of another form, which means it will not be considered their 8th album. They are also planning to do short promotions for the album. The exact date of release has not been fixed yet but they are planning to release it sometime mid-July.

Also, SJ-World had asked Leesmusic if they have any info yet regarding the special album and there isn’t. Once there is more info, SJ-World will begin taking preorders~
