GTA 5 Xbox One boxart appears on Amazon Germany

Update: now removed, no comment from Rockstar currently has a 1080p HD edition of GTA 5 listed for release on Xbox One and PS4. This is quite the turn-up, obviously.

The boxart is clearly a mock-up - the PS4 version carries an image of the Xbox 360's hard drive - though Amazon is a fairly credible source. It could be a placeholder, put up in advance of an official announcement. It could also be a fake, thrown together by some malicious intern for shizzles and gizzles.

Rockstar and parent company Take Two have repeatedly denied rumours about the existence of a next generation version of the game, with studio co-founder Dan Houser objecting that "there's plenty of power left" in Xbox 360 and PS3. Rockstar North does appear to be working on a game engine for "next-gen platforms", however, and Take-Two has an "extensive pipeline of unannounced titles" in the works for the new consoles.

We're mailing Rockstar for comment now. Why not investigate our list of confirmed Xbox One games, while you wait? Thanks, NeoGAF.

Update: has now removed the pages in question. There's still no word from Rockstar.
