1. Winter Soldier
It's been confirmed that The Falcon will make an appearance in Avengers: Age of Ultron, but in what capacity is unclear. With Captain America busy fighting Ultron and his army, it would be great to see Sam Wilson still on the hunt for the Winter Soldier, offering Cap updates on his progress. If that were to lead to a surprise cameo from Sebastian Stan, then it would be even better, and a great way of teasing what's to come in Captain America: Civil War. Any sort of nod to what's happening with Bucky would be a good way to reward fans who care about continuity, while also showing that Cap hasn't completely forgotten the mission he set out on at the end of his last movie just to hang out with The Avengers. Who knows, perhaps Tony Stark will find out that it was the Winter Soldier who assassinated his parents, creating a rift between him and Steve Rogers which nicely builds towards Civil War...
