This is probably just Tarantino thinking outloud rather than a serious film idea, but you never know:

“I’ve thought of prequels and sequels,” he said. “I had this great idea where we wait five years and come back not with the Bride as the main character, but Vernita’s (Vivica A. Fox) daughter as the main character. It would be fifteen years in the future, and the Bride (Uma Thurman) would be in a wheelchair.”
