There is a theory for wakanda forever that Nakia will be the next black panther because of one photo. Recently marvel posted a photo of a new black panther from the wakanda forever poster and it has a silver necklace with a different mask showing that is it not going to be the same black panther as before. This could be a valid theory because we know in the last black panther movie that Nakia can fight very well and there is also a rumor that she could be carrying t’challa’s baby. This would make sense as to why Nakia could be the next black panther and honor T’challa. this theory is also valid because at every comic con the lead actor or actress always stands to the left of the director and during this years comic con Lupita Nyong’o was standing left side of the director.
