There is a new mini series for Winter Soldier coming out in February 2014. It will be written by Remender and art by Roland Boschi.
Here is the article from Newsarama.
The Winter Soldier is returning to a solo series, just in time for the movie that bears his name, Captain America: The Winter Soldier. While the movie is hitting in April 2014, Winter Soldier: The Bitter March will hit comic book shelves in February 2014, an all-new mini-series written by current Captain America writer Rick Remender and drawn by artist Roland Boschi.
The story takes place in 1966, telling the tale of one of the Winter Soldier’s missions while Captain America was ostensibly still in deep freeze. That doesn’t mean the series won’t affect Captain America, though, as Remender tells USAToday it will “shatter” Steve Rogers’ world.
In The Bitter March, Nazi scientists rear their ugly head once more with a formula that falls into the hands of Hydra. S.H.I.E.L.D. agents Nick Fury and Ran Shen have to race against Soviet agent Winter Soldier to secure the formula and secure a major Cold War victory.
It'll be interesting to read a story where he is the Russian assassin, and not him dealing with the consequences of being that assassin.
