PlayStation All-Stars Battle Royale leaks again; Raiden and Sackboy spotted

PlayStation All-Stars Battle Royale has to be Sony's worst kept secret since the Vita; two more roster members have been uncovered thanks to a marketing slip up.

Reports suggest someone at Sony was a bit too quick with the "publish" button today, accidentally posting new content to the PlayStation All-Stars Battle Royale website before rapidly reversing the update. NeoGAF was quick to screengrab some of the site's new material before it vanished again.

LittleBigPlanet' Sackboy is clearly shown as both a character select icon and full character model, while the Metal Gear Rising: Revengeance version of Raiden is shown grappling with InFamous's Cole in a banner labelled "ultimate mach ups".

IGN reports users all posted images of the site on the official PlayStation Forums, but the thread was quickly shut down if so.

The images look pretty legit, and all the other characters have been confirmed, so it seems pretty believable - especially as Superbot has confirmed the last set of leaks as genuine, and the existence of the fighter itself leaked.

PlayStation All-Stars Battle Royale is due in late October for PlayStation 3, with a Vita announce expected. More character confirmations are likely to hit soon.
