Wonder Girls's 2nd Teaser for Comeback!

I just saw an update from JYPE's Facebook.
They released another comeback teaser for Wonder Girls!



So far, their teaser photos are getting more interesting.
This seem different from their previous song releases (eg: Tell Me, So Hot, Nobody, 2 Different Tears).

I'm really excited to see a newer side to Wonder Girls!
I can't wait to see what kind of MV their gonna release~ ＼（＾ ＾）／
I have high expectations from them, this time (after the silent disappointment from 2 Different Tears).

PS: I just loooove that hat. XD
