What that extra content will be hasn't been announced yet, but the game's active fanbase will certainly want to keep their eyes peeled for it. While there's definitely some double-dipping going on here, hopefully that retail content will also be available to download for people who bought the digital version of Rocket League. And as the game was originally released on the PS4 free for PlayStation Plus subscribers, there's a good chance that lots of players haven't shelled out any cash for it yet -- those that have become devoted fans might not mind dropping some cash on the new ultimate edition. We'll have to wait to find out how much it'll cost and when exactly it'll be released, though.
