Last year, we got Battlefield 4. The year before? Medal of Honor: Warfighter. The year before? Battlefield 3. The year before? Medal of Honor (Reboot). We will not be getting a new Medal of Honor this year, because Danger Close was shut down in June 2013. Danger Close developed the two recent Medal of Honor titles and, as EA Los Angeles, many of the previous Medal of Honor titles and many RTS games (Command and Conquer, Red Alert, Lord of the Rings: The Battle for Middle-Earth).
Many of their employees are now working at DICE LA.
So, when a new Medal of Honor title should be released, we get Battlefield: Hardline. A person with decent pattern recognition might believe that Battlefield, or its spinoffs, would fill the gap left by Medal of Honor. Not so, according to Patrick Söderlund, Executive VP of EA Studios. As was the case at E3, where both studios (DICE and Visceral) repetitively claimed that Battlefield: Hardline was the product (literally) of a fluke encounter and pent-up excitement for cops and robbers.
Of course, they do not close the door for annualized Battlefield releases, either. They just say that it is not their plan to have that be "the way it's going to be forever and ever". Honestly, for all the hatred that annualized releases get, the problem is not the frequency. If EA can bring out a Battlefield title every year, and one that is continually a good game, then power to them. The problem is that, with an annual release cycle, it is hard to get success-after-success, especially when fatigue is an opposing, and (more importantly) ever-increasing force.
It is the hard, but lucrative road.
