The photo above was taken from at an EBGames store in Australia, taking pre-orders for PC editions. Rockstar ships the game, posters and other marketing materials a few weeks before release. So with the shipment of the games, the store must have received this unannounced edition and put it up mistakenly. I submit that Rockstar do have a PC and next gen release in the works but are just waiting for the right time. The PC and next gen release will be superior to the current gen and announcing them all at the same time will take away the thunder of the current gen. Rockstar want to push their sales as far as possible with the current gen, because of it's huge install base, and then announce a PC and next gen version afterwards.
