Block B fans are sad as the guys has announced that they are not going to make their comeback. The guys tweeted on their official Twitter page which they wrote:

"Hello. It's Seven Seasons.

We have an announcement to make concerning the release of Block B's single [JACKPOT].

On April 16, we announced the delay of Block B's release and comeback schedule for single 'JACKPOT'.

However, in a situation in which the bereaved families of the missing and victims of the national disaster are suffering, the agency and members find it difficult to take on their new album activities. Thus, we have decided to cancel their single album release and comeback schedule.

The agency and members all made this difficult decision after careful deliberation and we sincerely apologize to the many fans who waited for Block B's comeback.

After wrapping up their schedule for their first solo concert '2014 BLOCKBUSTER', Block B will greet you all with a new album as soon as possible.

Once again, we apologize to the many fans who love and cherish Block B and JACKPOT. We ask the fans for their understanding.

We also offer our deep condolences to the victims and bereaved families who are going through unbearable pain through this accident.

Thank you."

While the guys are not promoting their "Jackpot" single, fans of the guys are still going to be able to purchase their album. The only thing though, not everyone is going to be able to get one because it is going to be limited.

Even though the guys will not be promoting and entertaining the audience for the music shows, fans can still watch their music video.
