If you look at the tweets and Facebook posts by Arrow, you do not see anything about Caity. Additionally, she is not mentioned for Comic Con. This can only mean one thing and that is not good news for Caity/Sara. I am afraid that it is R.I.P. Sara. ��
Well, she's present in the very first episode i.e 3x01 (must be towards the end of the episode) in her Black Canary costume.

This action character will initially be available at San Diego Comic Con and then through DC Collectables. I believe that Caity will be there. It is disappointing if they elect to eliminate / minimize her character. http://www.mtv.com/news/1866352/the-flash-arrow-action-figures/
Is Laurel ready to become the new Black Canary?
Sara may have given her the leather jacket before leaving Starling City, but that's all Laurel has so far. "If she does undergo hero training" says Kreisberg "it will be over the course of the season"
How much will Sara play a role in the new season?
Kreisberg: She plays a big role in the new season. We have her booked for three episodes and hopefully for more. We love Caity Lotz. She's so amazing. Watching the dailies of her in the premiere and seeing her back, it's always fun to see her. As much as her stuntwoman does, Caity really does get out there on her own and it's fun to watch.
