We're still a ways from a proper release date announcement, but at least we now know something we didn't. As VideoGamer.com reports, EA revealed during its latest earnings call that Battlefield 4 will come out some time during the company's 2014 fiscal year.
That fiscal year will run from April 2013 through March 2014. Since we already know the Battlefield 4 beta is scheduled to kick off in the fall of next year, we can deduce that BF4 will be out after September 21, 2013 but before April 1, 2014. With Battlefield 3, EA kicked off the public beta on September 29, 2011 and ended it on October 10. The game came out a couple of weeks later, on October 25.
A release next fall would definitely be nice, but I hope EA DICE takes its time with the sequel. Rapid release cycles for war-themed shooters may have padded the bottom lines of companies like Activision, but they haven't yielded particularly memorable games. While the Modern Warfare series tends to blur together in my mind, I have far more vivid (and better) memories of large multiplayer battles in Battlefield 3.
