Jason Latour will replace the long-term Captain America writer on the Marvel Comics spinoff from January's issue #15, it was revealed at Fan Expo yesterday.
Brubaker had already announced his plans to end his long run on Captain America with October's issue #19.
That left Winter Soldier his one remaining ongoing, contracted project as he turned his focus on his creator-owned material.
"Well, originally, the book was going to end around #14 or #15, because sales weren't as good as we'd hoped they'd be," the Brubaker told Comic Book Resources. "I'd been planning for that end for about three or four months.
"Then I guess sales stabilised, and the Cap movie [sequel] was announced, and everyone really likes the book and likes the character, so they want to keep it going. But in the meantime, I'd taken on outside comic work that was making my schedule harder and harder to keep up with, and so when Tom [Brevoort] told me they were keeping it going instead, I just felt like I needed to let it go.
"I struggled with it, and Tom and I discussed several possibilities of me staying, some of which I can't really discuss openly, because they concern internal workings of the company, but in no way was this an easy decision, and I feel bad if my readers think I'm bailing, because that wasn't the case."
Latour is better known in the industry as an artist. He collaborated with Cullen Bunn on a story in the 70th anniversary issue Captain America #616.
