What happens to Ahsoka?

I haven't looked into this, but at some point they will have to 'lose' Ahsoka Tano, as she doesn't appear in Revenge of the Sith, and I believe she is never mentioned from there on.
Does anyone know how she is 'lost'?
I am getting to like the character and hope they don't kill her off.
Although positive characters are often killed off in Star Wars it would be no surprise.
Does anyone know what is going to happen to her?

At CV a young girl asked Dave Filoni "What happens to Ashoka?" to which he didn't reply only George knows and possibly Filoni. Here's hoping she dies.

Carbonite, I bet. Can't make the kiddies cry too hard now, and hate Star Wars forever!

I hope she is sent off as a full Jedi to help some where far away. This is why we never hear about her again.

I believe something will happen to her - and it hastens Anakin's fall to the dark side.

Still don't care for her, but her new look and double blades makes her look better. I really think Anakin killing her would help his inevitable turn to the dark side.

Great idea!
