to resume, she does not jus release the album theres also, choreography, music videos, interviews, and live performances for those interviews the atack of the masive MEDIA, plus as some one else comented earlier, i also dont think we deseve it yet :(
Because making the promotion of an album requires a lot of energy and she probably doesn't have enough for the moment. But anyway, her health is more important than the album; so be patient and let her heal peacefully!
