@Katakon- I heard that it was confirmed that she wasn't, but I can't say for sure yet. I kind of hope she isn't and that Sombra is an evil character lol.

There's no confirmation either way, but if Ana were indeed Sombra, they would have likely used her code name as her name in the game (like they do with Angela, Gabriel, Jack, Amelie, and Lena). But, yeah, it's also unlikely that Ana, who's Egyptian and likely speaks Arabic, uses a Spanish code name for herself. But, you never know! Blizzard has yet to say anything on it, but I'm thinking if Ana were Sombra, they likely would have announced her as such.
