Earlier last month, SM announced that f(x) may be coming back to us this month.  

Now the label has provided fans with an update, stating that the now 4-member girl group will "shoot their new MV on September 11, the comeback is still undetermined." A rep from SM further related, "The exact comeback period hasn't been confirmed. But f(x) will start promotions for a new album within this year." 

Exciting news isn't it? Who here is hyped?
