Sticker Star seems like a cool name for the game. Glad to know it got an official name and reconfirmation of a Late 2012 release. Hoping to see tons of more info tomorrow.
By the way, I was on Nintendo' E3 website and noticed some cool pics on Paper Mario: Stick Star. Doesn't this art look nice? Seems the crown shaped character is called Kersti. Kersti seems to be Mario's first partner in the game. The description is the same for all the pictures by the way.
