Even though we're already seeing a competition of comebacks from many artists including�Rain and Lee Hyori, it's looking like the month of May will be just as competitive as April, if not more. With the two top stars likely going to dominate this month and June's FIFA World Cup approaching, many artists are looking to aim May as their comeback. After all, it'd be wise to avoid competition with Rain & Lee Hyori in April and also stay away from the dates of June 11th - July 11th, when Koreans will have their eyes glued to broadcasts of the FIFA World Cup. It is also now speculated that 2PM, who is planning to comeback at the end of April, will push back their comeback date to May instead of April because of Rain and Lee Hyori's delay of comeback from the naval ship tragedy. Artists who are scheduling to comeback in May include the Wonder Girls (May 15th), SS501 (May 1st), 2NE1, 4minute, Se7en and Son Dambi. Son Dambi for one has pushed her comeback twice - first she scheduled her return for�March, then delayed�to April, and is now shooting for a date in May. Regarding the delays, her agency stated, "It's not because of the naval ship tragedy; it's because we want to make Son Dambi's album more complete and perfect." Wonder Girls, who originally planned to come back in April, will release their U.S debut album in countries around the world, including Korea, on May 15th. The girls are planning to cross promote between America and Korea. One of the related sources from the music industry speculated, "In my opinion, it's useless to waste your energy coming back in April. A lot of the agencies are organizing their artists to comeback in May. In this coming May, we will see one of the fiercest gayo battles we've ever seen." May looks like it will be one heck of a busy month for our k-pop artists and groups.
