Face it. T'challa having a solo right now is not the right or correct thing to do in my opinion. At least, not until he is a major part of a team...then getting a solo. This is a way to get him into the Avengers, I think. Ironman could be doing the same thing as T'challa, working on solution.
We don't know what he is going to do, it might be nothing at all. That's highly likely, but there is a chance that he does something in Aaron's issues and even in the other book VS. Because at this point they have not even announced most of the titles. There is like 12 issues plus however long Vs is...
So I'm wait and see...if he doesn't do anything it's par the course. If he does, great. But the real story is after the event...and him being a part of the event, sets him up to be a part of the aftermath organically. Which to fanboys, matters I guess.
Plus, I think that Aaron, likes Action-Black Panther. He is only one dude though...and there are a whole bunch of creators...controlling the story.
I'm still hoping that Aaron gets to write him on a team, or maybe Hickman. When the new creative teams are announced. All of this is Marvel answer to D.C's 52. But part of the Marvel brain trust has that same stupid "big 4" mentality vs. guys like Aaron who just write.
