President Randy Pitchford said it would be "distracting" to update fans on its multiple franchises, including Duke Nukem and Brothers in Arms: Furious Four, when it has Borderlands 2 and Aliens: Colonial Marines shipping within the next year.
"We haven't been talking about [Brothers in Arms] and we won't for some time," he told Digital Spy at PC expo Rezzed in Brighton.
"I wouldn't expect us to be talking about that until either before or after Aliens ships.
"It's evolved quite a lot, and it's seems like it's going to evolve some more, so we won't be talking about it again until we know what it's evolving into.
"Because when we talk about it again, it'll seem very different, and so we want to see where it gets to, because we're not sure how different it's going to get, but we're having a lot of fun with that.
"It's exciting to us, but again, it's just too confusing to talk about it."
Pitchford said that it is "helpful" to have Gearbox working on multiple projects, as the studio can share resources and is always at a peak period of working.
"One of the neat things is that there is the same scaffolding no matter what project you do," he explained.
"Imagine you're going to build a building. The building is unique, and all the material is just for that building, but for this material you've got to put it on trucks and drive it out there, and all the people working on it need hard hats. Imagine that every time you build you need new trucks, and you buy hard hats.
"When you do multiple things, we can use the same hard hats and use the same trucks. What this means is if those are separate projects with complete separate budgets, that's all wasted investment.
"Whereas we can get more bang for our buck, and our games are getting better as a consequence of being able to leverage the scaffolding that is the same across multiple projects."
Pitchford continued: "The other thing that happens is that a project starts with a small number of people to figure out what it needs to be, and then as you figure that out you begin your ramp so you can build all of the vision, and then it ramps down at the end.
"If you're a single project company, you have this arc where I have this many people, you then hire and hire, and if I'm responsible I have to then fire people [when the project is over] and that's terrible.
"The other option you have is drawing a straight line [on a graph] which means you have people that can't do much [at the start of a project], they're all kind of bored and I'm spending money on them.
"Then, when I need this amount of people [later in the project] I'm stuck at that level of the line and I'm not getting that peak effort. So I have to make compromises and I'm in that pit again where I'm wasting money, so that's not a good solution."
Pitchford concluded: "With multiple projects, you can [peak continuously] so as one project is coming up, another is coming down, and it works out and levels everything out nice."
Brothers in Arms: Furious 4 was first revealed during E3 2011 and was recently assumed to be cancelled after publisher Ubisoft pulled trademarks for the game.
Set during World War II, it follows four soldiers who face an "experimental Nazi army conceived in secret" while attempting to track down Adolf Hitler.
Gearbox Software's next project, Borderlands 2, will be available on September 18 in North America and on September 21 in Europe.
