It seems TaeTiSeo's comeback will be happening soon! 

On September 4th, Newsen exclusively reported that, Taeyeon, Tiffany and Seohyun are in the last stages of preparing for their new album. It's also said that their comeback will be in early half of September at the latest, following Chuseok holiday. 

SM Entertainment responded to the news,"We're preparing for their comeback with mid-September as the target, but the date is still undecided". 

TaeTiSeo's comeback has been highly anticipated since it's the sub unit from Girls' Generation whose name is considered as one of the best girl groups in Korea. Until the official news come out, you can catch the girls on OnStyle's reality show 'THE TaeTiSeo'
