The studio's general manager Karl Magnus Troedsson made the announcement at GDC Europe, where he told attendees that fan feedback and market research will be taken on board for the sequel.
"There's a lot of things inspiring us as to how the franchise will move on. Everything from fans' feedback, to market research and, of course, what we want to build ourselves. It's not just one single thing," he said.
"And, yes, I know Battlefield 4 is probably the most creative name we ever could come up with. I can't comment any more on that game because it's all secret.
"We still want to stay in this genre, the modern day as it is. We feel this is a place we can be and continue with the series. Battlefield 4 can live in this space and be very successful."
EA officially announced Battlefield 4 last month. Customers who pre-order the Limited Edition version of Medal of Honour Warfighter will be granted access to a beta launching next autumn.
