SM Entertainment revealed�on the 23rd via TVXQ's homepage, "2011, TVXQ will be returning to you all." SM released a statement saying,

"After the 3 TVXQ members left, for over a long year, both U-Know Yunho and Max Changmin have refrained from musical activities. The two members as well as the company wanted to keep TVXQ alive, thinking about the never changing hearts of our loyal fans who have waited a long time. As indicated by the ruling, all of TVXQ's activities need to be done through SM, unfortunately, the three members that left have regretfully not responded to any of our offers for activities as TVXQ. After long and careful consideration, we made this decision. For U-know Yunho and Max Changmin, who never left and kept their dreams as TVXQ, we have decided together with the two members to keep�TVXQ�alive. No matter what happens, we believe that�TVXQ�should continue for the love and trust of the fans who created�TVXQ�together with us. We are not ruling out any possibilities in the future. Continuing�TVXQ�is the best way to repay the fans who love and waited for�TVXQ."

The two member TVXQ is scheduled to make a comeback in January 2011. Source: TVXQ Official SMTown Website
