SM Entertainment has big plans this 2017 beginning with NCT and its subunit NCT 127. It would be folly for SM Entertainment not to include one of their best selling groups, EXO, into the fold so you can expect the group to stay active next year. Furthermore, SM has planned numerous epic comebacks as the legendary girl group from the 90s, S.E.S is set to return in 2017. Not only that, SM is also bringing back its 'golden lineup' since several members of TVXQ and Super Junior are set to finish their mandatory military service.
