UPDATE from Philip: I visited with Amy Allen today in Dallas and she denied this report from April 25 in its entirety.

From a fan at Celebration III:

I met Amy on Saturday and got her autograph and the usual conversation. I asked her about her status in ROTS. She said that (highlight to read) she "does not die" and that she is "hoping that George will call her, in regards to the television series" and that they have briefly discussed a role for her. Whether that is a starring role, or a supporting role, Aayla Secura is mostly confirmed to be a character in the new series.
