I really don't see the problem with Ahsoka. Why would she be in the movies or even mentioned? She's around for the Clone Wars, which takes place after EII and prior to EIII. I presume by the third movie that she's either been reassigned or promoted or killed off, but I can't think of a scene in the movie where Anakin really needs to mention her or where she "should" have come up. You don't see Anakin talking a lot about anyone in the movies other than his mom, Padme, and Obi-Wan and yet he had childhood friends on Tatooine, training and missions with other jedi, etc.
As for the show, I'm still hoping on a storyline that centers around Fett learning his trade and/or the continuation of the Jedi purge.
