At GDC Europe, DICE manager Karl Magnus Troedsson affirmed that Battlefield 4 will remain based in the modern day. When asked about why the studio decided to go straight to Battlefield 4 instead of going back to Bad Company, especially after the 6 years between BF2 and 3, he replied:
“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.
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.
That doesn’t mean there might not be a Bad Company game again in the future.”
