The thing with Walker is, and I know that it's not a lock, especially given how calculating Disney is and how Four Quadrant and safe (Sorry, it is the truth. Safe means calibrated to the Nth degree to give each demo something whether it's organic to the plot or characters, never doing something truly controversial, allowing only so much depth and shaving off any REAL sharp elbows of the characters and glazing it all with a heavy coating of broad humor...) so much of Marvel's product has been, there is a lot of good dramatic material to mine ESPECIALLY in today's climate in the U.S.
For those that don't know, Walker as a character is... He'd be a Trump supporter let's say. He's a go with his gut reactionary, an America, love it or leave it type. He was introduced as a caricature almost of what people THINK Capt. America should be. His time in the role was very stage managed to manipulate the public into accepting him as Cap.
In the modern world... That's a lot of fertile ground for commentary if they don't chicken out.
