Enter The Winter Soldier: Bucky Barnes Lives !

Captain America and Bucky Barnes haven't had it easy. Both have made great sacrifices for their country since they first dressed in costumes and began fighting evil forces. In the 40s it appeared both made the ultimate sacrifice, but has overcome death itself. Captain America was found decades later by the Avengers and began his fight once again.
In 2007 when Captain America discovered the amazing truth about his partner Bucky. Bucky hadn't died all those years ago. It turned out a Russian submarine had found his body, which was only missing one arm. With no memory of who he was, Bucky was transformed into the assassin known as the Winter Soldier. Kept frozen cryogenically between missions, Bucky had only aged a few years until his encounter with Captain America.
Bucky overcame his programming and regained his memories (with Cap's help and a cosmic cube). He even took on the mantle of Captain America when the Red Skull launched his attack that made it seem as if Cap had been killed. When faced against the Red Skull's daughter, Sin, possessed by an evil Asgardian spirit, Bucky; now the new Captain America, becomes more of a hero than Steve Rogers ever was. A recent Marvel teasers asked the question, "What if there was more than Bucky?" With the solitary red star on the teaser, DNA extracted from Bucky Barnes during The Winter Soldier Program, and with seeds planted in the Captain America series by Ed Brubaker, it looks as if Cap might be facing some other 'Winter Soldiers.'

Bucky returning from the dead is inevitable, and has happened based on the marvel comic books. Bucky's body was found alive and in frozen animation, he was examined by Russian scientists in 1945 in the hopes that he had the Super Soldier Serum in his body. Despite having no memories, he still retained his muscle memories and could move and fight as before. He was kept frozen until 1954 when Project Winter Soldier began. Bucky was fitted with a bionic man and programed to serve their agenda. Passing as an American, the Winter Soldier was able to cross 'enemy lines' and complete his assassination missions. In 1957 it was noted that he was started to get more curious, perhaps trying to fill the gaps in his memory. This was the main reason he was kept in stasis in between missions.
With all the work the Russian government put into creating him, it was a Russian Conspiracy all along to use Bucky Barnes for the Winter Soldier Program. They would need suitable subjects but only having one soldier would be like putting all your eggs in one basket. Sending out their only soldier and risking him getting captured would be too high of a risk. They had no one as skilled as Bucky, which is why they rescued him, and prevented his death, to use him as a living weapon.

The scenario has to do with something known as Project Zephyr (mentioned in Captain America #619). When Bucky was held in a Russian gulag, it turned out that he held the secret of the project locked in his brain. Enhanced sleeper agents had been created during the Cold War. Bucky, brainwashed as the Winter Soldier, helped train them. He trained them on advanced weaponry, hand-to-hand fighting, improvised explosives and most importantly, how to act like Americans. They were never used because the Cold War had ended and they remained frozen in sleep chambers in their secret location.
The warden at the gulag, Colonel Rostov, set things in motion to get his hands on Bucky. Bucky was the only one left that knew how to awaken the sleeper agents. It was Rostov's goal to use these human weapons of mass destruction for his retirement fund as he has seen enough destruction in his life. Selling this information to the enemies of America will obviously lead to new challenges for Captain America, and make him realize that he needs Bucky's help to stop them; but first, Cap's mission is to safe Bucky, by unbrainwashing his partner, and help to restore him to the hero that he once was.

We've only seen a little of Cap dealing with the loss of Bucky. Wearing the suit and carrying the shield once again will be a constant reminder that Bucky may have survived. It was a vision that Steve had when he was fighting Red Skull that showed Bucky alive in his future, dressed as the Winter Soldier. Steve figured as long as Bucky remained wearing the Captain America outfit, that vision will come true. Despite this; the truth is, Cap didn't fail to keep Bucky alive. He was carrying that guilt in his gut for years, until now! Fighting other Winter Soldiers could be a massive boost to Captain America faith in Bucky abilities, to return as a hero. And if these soldiers can easily blend into crowds, finding them won't necessarily be an easy task, and neither will reaching out to Bucky.

The other question is where is Bucky's body being kept? The current Captain America series takes place after Fear Itself (since Cap's shattered shield appears to have been repaired somehow). We all can be sure that Bucky has return from the dead somehow; (possible thanks to the cosmic cube), and we have seen who actually examined his body. Let's just hope and pray that we will be seeing clones of Bucky as the other Winter Soldiers.
A way to add to the shock of more Winter Soldiers would be if they were other heroes thought to have died, just like what happened originally with Bucky. If Cap had to fight other fallen comrades that had been brainwashed and trained to be sleeper agents, he's going to need some serious therapy after all this. It would make for a interesting twist but it could end up being a little too cliché if others close to Cap suffered a similar return from the dead that Bucky did.
We'll find out in January just what is coming. It's possible there might be an announcement at New York Comic-Con this week. Let's hope Captain America and the rest of the world will be ready to deal with the return of Marvel Comics's coolest sidekick!
