This shot was purportedly taken at BT Games in Johannesburg, South Africa at the Cresta Shopping Centre, and not only shows a logo for God of War IV, but asks gamers to pre-order it.
It's worth noting that the genre specification on the box marks GoWIV as a "shooter". Whether this is a placeholder, a mistake or... well... a sign of a very different God of War game than you may expect remains to be seen.
Of course, the boxes could be on-the-fly fabrications by the company, the picture could have been altered, or there could be some other explanation. But if it's real, it appears BT Games has jumped the gun on putting out their God of War IV promotional items.
