Marvel uploaded an interview with Cort Lane and James Mathis III from Comic-Con. They start talking about Black Panther's Quest around the 4:30 minutes mark. Looks like the second half of the Season will feature T'Challa traveling through time and meeting other past Black Panthers. Also, Lane mentions Shuri will be appearing in another show they recorded recently.
The only other show I could think of Shuri popping up in where they might still be recording for would be Marvel's Spider-Man (although I guess she could make an appearance in one of the Marvel Rising specials), especially since Daisy Lightfoot was already part of the show as Electro .
