I thought that was likely the case because I thought I remembered someone mentioning at some point that Black Panther is somewhere in Universal. With the caveat that we don't know the true intricacies of the rights deal (and I'd bet that Disney and Comcast probably wouldn't agree on some of the finer points), I think it raises the interesting question of Wakanda vs. Black Panther as far as a land goes - particularly with there being a Wakanda
Disney+ series in the works that might not include Black Panther at all (no idea on that - just a guess that I could see them referencing Black Panther but not having the character in the series at all). Would the rights potentially allow for a Wakanda land/area devoid of Black Panther? I realize unlikely for multiple reasons, but just an interesting concept (kind of like Galaxy's Edge without Luke/Vader, etc. - if there were rights limitations to the original trilogy or the first 6, would Galaxy's Edge still be okay since it doesn't involve anything from those movies - Chewbacca and the Millennium Falcon notwithstanding).
