This alleged 'leaked' schedule reads,

February: Girls' Generation's Taeyeon & Red Velvet

May: Super Junior Yesung's solo album & Super Junior-M Henry's album & BoA's full-length album

June: TVXQ & S.M.ROOKIES' debut album

However, SM Entertainment spoke up to say this circulating schedule is not an official one from them, and that the listed agendas are not something that the agency has confirmed or finalized. A rep also denied the rumors of it being possibly leaked from an internal source, stating, "The information spreading online regarding SM's lineup for the first-half of 2015, which has been spreading online, has not been leaked from someone within the agency."

The only artist officially confirmed so far is SHINee's Jonghyun, who will make his solo debut with his 1st mini-album 'BASE' on January 12.
