"When this sequence was cut from the edit of Episode III, Shaak Ti's life was spared. She can still be seen in Episode III, as a tiny tabletop hologram on Kashyyyk, when Yoda is remote-conferencing with the Jedi Temple.
"Although her earlier death at Grievous' hands was completed and included on the DVD as a deleted scene, it should not be considered the canon version of her fate. This is because she is still visible later on in the movie as part of the Kashyyyk hologram. The deleted scene on the DVD, "General Grievous Slaughters a Jedi," should instead be considered an interesting look at what might have been."
