What Happens to Ahsoka Tano?

[Tac]

In a deleted scene from Episode III, there is a female jedi character held hostage by Count Dooku aboard the spaceship holding the captured Chancellor Palpatine.  This scene takes place in a corridor moments after Ob-Wan and Anakin board the ship and are searching for Palpatine.  They come across Dooku and the female jedi that resembles Ahsoko.

Dooku impales the female jedi with his lightsaber killing her.

That might anwer you're question but just leads to who she is?

That would be different jedi..different species from Ahsoka. Shak'ti or something like that as the clip goes.

She and Anakin have developed a deep relationship.  How is it that there has never been a mention of her in any Star Wars movie?

Same reason why "Starkiller" isn't mentioned in any of the Star Wars movies as being the leader and inspiration for the Rebellion (Rebel insignia is Starkiller's family crest).  These are new additions to the Star Wars canon even though it breaks the official continuity of the Star Wars story line.

Lucas has declared anything not in the films is not Canon, and he does not abide by it. 

That is not true.  For example, the story of Force Unleashed and Force Unleashed II are part of the official Star Wars canon, as well as numerous officially sanctioned novels and comics in addition to the Clone Wars cartoon.

Every officially sanctioned Star Wars game, movie, novel, comic, etc. has to go through the Lucas Licensing department to ensure the products fit the official canon.
