A different "illegal fwd pass" situation

[rbmartin]

Did anyone see the play in Chargers vs Raiders where the S.D. wide reciever
caught the ball and went down with no contact from defensive player. The reciever then stands up and spins/throws the ball to the turf (toward the goal line from where he is standing). The defensive team quickly covers the apparent "fumble".
After conferring, the officials rule at was an "illegal forward pass" and not a fumble.
While probably technically the correct call, what are the chances that the rule covering this situation will be revised in the offseason?
