Whether this is good or bad, only time will tell.
Let not forget, no matter how bad CCM/KKS is in handle PR or issue, they are still the one who brought T-Ara from a rookie to where they are now, without them there may not even have this 7 girls coming together. Rather than using my brain to judge whether this is the right move from CCM/KKS, I would use all my focus to supporting T-Ara.
Hope that this come out good, even if it not, I'm prepare to stand by T-Ara even if it against the world.
