EA has no plans to try and make a new Battlefield game every year following the release of the most recent "Battlefield 4." The developer doesn't want to release an annual title if it can't guarantee that there won't be a dip in the quality of each installment.
EA CFO Blake Jorgensen addressed the question when asked by an analyst at a UBS conference (The full transcript of the interview Q&A can be found HERE via Seeking Alpha).
"The challenges are you've got to most likely do it out of two studios because it's hard," he said in reference to rival publisher Activision Blizzard splitting Call of Duty development between Infinity Ward and Treyarch to produce an annual title in that franchise each year. "It's a two-year project. Battlefield takes us about two years to develop and so you want to make sure that you're sharing talent across studios, so you keep [the] core talent of the product and the experience for the consumer there. You also want to be really careful that you don't destroy the franchise along the way. You got to make it exciting and different, but at the same time you want to make sure you maintain a great franchise."
He continued the discussion saying "And Battlefield is a product that doesn't just sell once, it sells for 24-months associated with not just Battlefield, but all the additional Battlefield Premium activities that the consumer wants. So you've got to be careful that you don't destroy some of that tail that is on the Battlefield product."
According to IGN, the Swedish-based Battlefield creator DICE is likely to be tied up working on "Mirror's Edge 2" now that "Battlefield 4" has been released. It's new L.A. studio is taking on the task of creating a new "Star Wars: Battlefront." This means that if the franchise wants to go annual it will need another developer's help.
