While WandaVision already had the right to a first spin-off focused on the character of Agatha Harkness (Kathryn Hahn), Marvel has decided to expand the universe of the series by developing a new project.
According to information from several American media, Marvel and Disney+ have given the go-ahead for a series based on Vision and with the working name Vision Quest. In this series, we would follow White Vision as he tries to regain his memories and his humanity.
Paul Bethany, who plays the character in the MCU and in WandaVision, is of course tied to the project. Deadline also suggests that Elizabeth Olsen could take part in the Vision Quest series. Confirmation (or not) in the coming months.
