Entertainment Weekly reports that while talking to an Italian television show, director Quentin Tarantino confirmed that he plans to revist Uma Thurman's character in Kill Bill 3. Tarantino wants to have a ten year gap between the release of Kill Bill 2 and Kill Bill 3 (some sites are mentioning a rumored title of Kill the Bride), and that would put the release some time in 2014. That would still give QT time to make another movie before then. In 2014, Uma Thurman will have aged to 44, and her daughter from the first two movies will have aged as well. There are several rumors about what exactly the third movie's plot could be about, most of which involve characters from the first two movies getting revenge against The Bride for the violence she inflicted on their lives.
