No no. This is merely speculation. EA has announced both Dice and Visceral are currently working on Star Wars titles. I certainly don't expect Visceral to make a game like Battlefront, so the most likely company to be in charge of Battlefront 3 would be DICE.
My argumentative nature precedes me though. I'm still curious why you targeted me as someone to mention needing Battlefront in my signature... though now that I think about it, it occurs to me that you must be referring to the picture requesting sequels. Stupid me forgot about it. I actually made this image back before Battlefront 2 was even released, but at the time I also designed it with the intention of only focusing on single-player centric games as well. If I were to do a similar picture today, I would want to include Battlefront, but without a key figure to represent the Battlefront series, more likely I would go with Knights of the Old Republic myself.
