The current plan is to have Goldberg signed and used in the WWE 2K15 video game, which is set to release in the fall. Officials are trying to make this plan similar to what they did with Ultimate Warrior last year, as they promoted him heavily.
Furthermore, WWE wants to promote it at SummerSlam and continue to market and build the signing of Goldberg all the way until WrestleMania 31, which could be a match and/or a Hall of Fame induction.
