With their highly-anticipated comeback inching ever closer, the Wonder Girls will finally be returning to Korea within the week! A representative of JYP Entertainment stated, "The Wonder Girls are currently spending busy days filming for their TV movie, 'The Wonder Girls at the Apollo'. If there aren't any additional schedules to be added, they will be returning to Korea within the weekend and begin preparations for their comeback." The Wonder Girls are up against several girl groups like SNSD, Orange Caramel, and T-ara.  As such, an eye-catching concept is a must in order to stay in the spotlight.  The Wonder Girls are known for their retro concepts now, so many are wondering what they'll be bringing out next. The representative revealed, "The album will be produced in a movie OST format. We'll be planning our concept to fit around the feel of the song, so as opposed to retro, we feel that it will be more pop.  The Wonder Girls will definitely be coming out with a new image, so please look forward to it."
