It sounds like Marvel is willing to wait on Ryan Coogler before making Black Panther 2
Some Marvel movies, particularly early on, feel like they were constructed by Marvel Studios going down a list of important bullet points from the comics rather than being a personal work directed by an actual human, but the company does seem good at recognizing the benefit of allowing a filmmaker to put their stamp on something—at least until they make an Iron Man 2 or an Age Of Ultron. To that end, Marvel Studios head Kevin Feige seems willing to sit back and wait until Ryan Coogler is ready before moving forward with a sequel to Black Panther, even though Feige could probably make some quick cash by just calling up a gun-for-hire director and dumping out a cheap sequel next year.
