Closest thing we've heard is rumors that Letitia Wright might be playing Shuri in the MCU. That hasn't been confirmed, however.
Outside of that, nothing Shuri-related moviewise at the moment. I really hope she's in it. There's no reason for her not to be there. Her father was killed, and killed in foreign soil by a foreigner after he decided that Wakanda shouldn't be isolationist anymore. Not to mention there will be a shakeup in leadership, with T'Challa now at the helm.
