Parece que Battlefield 4 se desarrollará en un entorno moderno al igual que Battlefield 3. Karl Magnus trabajador de DICE afirma que la guerra moderna es popular, y el Battlefield 4 prosperará.
“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.”
“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 at GDC Europe. “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 games because it’s all secret.”
Como pone en uno de los comentarios de battlefieldo "Battlefield 3.5", nada que no pudiera haber salido en una update o unos DLCs.
