Final Fantasy XIII Definitely to Feature DLC?

It seems that GameStop has managed to confirm something that Square Enix has not, as of yet. It seems downloadable content will be coming to Final Fantasy XIII. Who would think that a little thing like case images would be able to reveal so much?

On Gamestop.com, the back of the case for the 360 version is now viewable. Upon inspection, one notices that it has all of the usual features that would be expected of a 360 game. What wouldn't be expected is the little box with the orange text: game-content download. Square Enix has been asked about DLC for Final Fantasy XIII before, but said no more than that they were considering it, but nothing was definite. Certainly seems more definite now.

I've e-mailed a Square Enix rep, but I won't hear back until at least tomorrow, I'm sure. Until then, take a look for yourself at the back of the case below.
