During Gearbox's panel at PAX Prime, it was announced that Brothers in Arms Furious 4 hasn't been canceled, but it's not the same game anymore.
Studio executive Randy Pitchford told CVG earlier this year that Furious 4 "has evolved, I think people are going to be surprised by what they'll see, and it's still evolving."
That was said in July, and it seems the game has evolved so much that now it requires a new IP and name change. During the Gearbox panel at PAX Prime, it was announced that Brothers in Arms Furious 4 is now a completely new game.
The new game will still contain references to Brothers in Arms, and fans will recognise these details, but the new direction that the evolution has taken the game into has separated it from the Brothers in Arms franchise.
Speaking to Kotaku, Pitchford explained "that when the game re-emerges it won't be a Brothers in Arms game at all."
Pitchford further explained that by separating from the franchise the team could "go wild with new features," and hinted that the new game could see a hybrid genre, akin to Borderlands half RPG, half shooter, but Pitchford wouldn't go into further details on the matter.
It is expected we will hear more at the Gearbox community day September 15.
