This does make sense... She's got three more singles until her 50th one. If she plans her year out right, she can release two more this year, and then her 50th single next year. She did a 30th single tour with "A MUSEUM". 50 seems a lot more special than 30, imo. She knows she can sell out concerts in other parts of Asia. More concerts = more money, and more money = better stage productions, videos, etc etc etc.

Plus, artists always plan out things waaayyyyy in advanced. They have to, really, to schedule everything correctly and make sure nothing overlaps. That's why actors are always attached to projects at least 6months to a year in advanced.
