According to SuperBot president Chan Park, he explained at PS Blog, “There was an unexpected and unintended leak in our beta that allowed fans to be able to see some additional content. We’ve enjoyed reading all of the fan reaction and are thrilled that so many of you are excited to learn more about our character roster and level mash-ups, however we are still in development and the leaked content does not fully represent the final product nor the incredible efforts that were made to make these elements truly spectacular. This will be evident in the coming weeks as this content is officially revealed, beginning with our next character announcement at Gamescom in a couple of weeks.”
We look forward to the official release of PlayStation All-Stars: Battle Royale with bated breath.
