When Pitchford was asked if we will hear about the new IP soon, his response was “It depends on how you define soon.” This is a rather ambiguous answer, but he then followed up by saying, “You’ll see it before the end of the generation!”. Unfortunately, we don’t know much about the game other than the fact that “it’s extremely different to what you’ve seen from us.” Of course, Gearbox will be “taking advantage of what [they have] learned" with their previous games.
Brothers in Arms was another popular subject at the conference. Gearbox confirmed that a new Brothers in Arms was indeed being worked on. One of the main focuses of the new installment is authenticity. Unfortunately, Gearbox seems to be facing a lot technical and financial barriers. Before much more can be done with the game, they need to find game studios to partner with for development and publishing.
