[Update: There's a rumor doing the rounds on Reddit at the moment which suggests that Borderlands 3 will be revealed on June 10 for a September release alongside an image that appears to announce the game. The image that's been posted looks, to us, highly suspect, but the date on which the game is being rumored for announcement is smack bang on the day of Microsoft and Bethesda's E3 press conferences.

 A reveal on Bethesda's stage is unlikely, but Microsoft's? There's a chance. We would certainly take this with a grain of salt at the momentThough the post has since been removed from Reddit, it can still be found on Google Cache.]
