Revenge of the Incredible Hulk (originally titled Rebirth of the Incredible Hulk) was reportedly a planned sequel to The Death of the Incredible Hulk. It was set to feature the Hulk being brought back to life, in which the Hulk would have David's mind. As of July 10, 1990, the script was being written. The script's writing was put on hold when Bill Bixby grew sick, and was canceled after Bixby's death.
It is also said to include She-Hulk.
Another sequel, set to feature Iron Man, was also rumored to be planned.
