Battlefield 3 core gameplay designer Alan Kertz, whom we’ve featured many times here on BF3Blog, has been very active in sharing his thoughts and ideas about Battlefield 3, most noteably, future updates and weapon changes. Now Kertz has revealed via Twitter that he has left the Battlefield 3 team, and has moved on to other projects at DICE. He didn’t mention what projects those may be, but one could speculate on a possible sequel to Battlefield 3 (Battlefield 2143, perhaps?), or even Bad Company 3. Kertz said that the Battlefield 3 team is still “diligently working on BF3″.
