2K has released a five and a half minute video detailing some of the early development history of Borderlands: The Pre Sequel. It walks you through the details of which studio is doing what and is replete with long shots of the offices of the development teams (if you look closely you can see the good bits of Alien:Colonial Marines that were left out in the background of the Gearbox studio clips).
It's a bit drawn out and a bit breathless about the game but it does include a lot of detail about the backstory of the game and lots of new gameplay footage which makes this worth your time if you are a Borderlands fan.
