The announcement by EA's CEO about the largest development team in Battlefield's history and the collaboration with EA's Motive studio on this project suggests a strong commitment to the franchise's success. This could lead to increased investor confidence in EA's future revenue and stock performance, especially with the anticipation building around the game's announcement and release. The transition from Battlefield 2042 to a new installment could rejuvenate the franchise and attract both old and new players, potentially boosting EA's stock in the short term.
