Redditor JimmijTheRustler just up and published that image of what appears to be the official box for the upcoming Mists of Pandaria expansion to World of Warcraft.
It looks legit — that UPC barcode checks out. Yes, that was submitted very early this morning — however, on the World of Warcraft forums, a reader has pointed out that the number sequence follows the one Blizzard has used ever since it released the Battle Chest. And yes, this has been rated T by the ESRB, so that part's legit, too.
The tipster who put this on Reddit suggests that the "Mists of Pandaria dissipate this [winter]", but whether that means a release or just a general revelation of the expansion's details — including its release, who knows. The expansion did enter a closed beta in March.

And so, it begins... The mists of Pandaria dissipate this Summer. [Reddit. h/t Sgt.LulzJager]
