Who will be the next Overwatch hero? (Overwatch)

Good day. Who do you think will be the next hero Blizzard will bring to Overwatch? There are several versions here. For example, Sombra is Farrah's mother. she is supposed to be a support hero. In addition, on the map "Temple of Anubis" there is already a dossier with her photo. Most likely, she will be the next hero, but there are other versions. And what do you think?
