Ben Cousins (EA General Manager for Free To Play Branch):

So yes, on the 31st of March anyone who owns a previous Battlefield game will be able to log into their EA account and get access to the Battlefield Play4Free beta. Then there are a couple of other phases. There will be a code published on Twitter and Facebook on the 2nd of April, and then we’ll go to open beta on April 4th. We’ve got three maps to start with, our version of Sharqi Peninsula, Gulf of Oman, and Strike At Karkand. We’ve got really in-depth skill trees, four player classes, and really that’s just the beginning for us. We’ve got extensive plans, such as adding a server browser before the summer, and adding in clan support features. That’s another difference between free-to-play and full priced packaged good: launch is the start for us, not the finish.
