YEAH! I saw their 'Mamacita' teaser and their promotional picture. 

YAHOO!!!!!!!!!! Although I am Donghae and Kyuhyun fan, I think in this picture Heechul looks the best out of the members. But poor Yesung, I knew he couldn't appear in this album because of the army service. I think I'm gonna cry but in really upset way because they have made a real comeback!

As I was saying, they will release this song on August month. Yosh, I will wait for this to be happen. See ya!
