Overwatch news this week has confirmed that the Orisa release date has been set for next week, March 21.
Blizzard just announced that Orisa would be released next week.

"Orisa serves as the central anchor of her team, and defends her teammates from the frontline with a protective barrier".
The latest behind-the-scenes Overwatch video goes more in-depth with the newest hero, Orisa.
Fortify is a pure tank ability, reducing Orisa's damage intake by 50 percent and making her immune to attacks that would cause her to move position or fall off a ledge.
Orisa launches a graviton charge which she can detonate, slowing nearby enemies and pulling them towards the explosion.
Previously Orisa weapon magazine size had decreased from 200 to 150, while the cost for her Ultimate, Supercharged, also increased by 15 per cent.
