Not all of you still complaining about Red Velvet's future

They are going to be fine, they are a balanced group, some good vocalists, some are serving good visuals and others good dancing, even Yeri is serving youth.
I know they will never reach SNSD, 2NE1 or Wonder Girls kind of succesful but i'm sure they will be huge, like f(x), 4minute, T-ara, Secret or Miss A back in the day.
