Though it seems to have disappeared since being screen-capped, it looks like Sony was writing an article on the Playstation Blog that shows the Playstation fighter being delayed almost a month.
Originally, Sony had planned to release Playstation All Stars Battle Royale in late October; the 23rd to be precise. Instead, we could be seeing a release right around the Thanksgiving holiday. Could the delay be because of the recent beta test having a large amount of issues? For what can be said, this is only a rumor until Sony tells us otherwise about the game.
