I agree. Joss has moved on. At most you'll see her in one of the Buffy-followup TV movies that he is considering (but not as the main character).
On the subject of Buffy, today I caught the Christmas episode from Season Three for the first time. What a great episode. I had always thought that Angel was pretty lame during that whole season, but that episode brought his character into better persepective. The appearance in that episode of the First Evil, taking on the form of the dead, also made the whole 7th season make far more sense.
