I'm really excited about the new season, it really has evolved with the last few seasons and the producers seem able to walk the fine line between what the fans want and what George decrees. I can't help thinking that we might see the end of Ahsoka, given the timeline her exit/death has to happen eventually to be big enough of a jolt to Anakin and allow enough time to pass after the event to counter why her existence doesn't rate a mention by the time ROTS rolls around.

It looks like there is a fierce battle between her and Ventress, maybe thats how they both meet their ends? It took me a long time to warm to Asohka (and I'm sure I'm not alone) and get over the whole 'sky-guy' "snips" thing, but she's probably gone through more character development than any of the legit characters.
