I'm really hoping Sam goes back to the Falcon for good. I understood Bucky as Cap because the Winter Soldier wasn't really a viable identity, he didn't have much history past WWII and Steve was dead. But Sam IS the Falcon and should be proud of that. He's accomplished a lot and made a name for himself. He shouldn't be living in someone else's shadow. As we've seen time and time again, Steve Rogers (pre-Hydra retcon) is Captain America and Captain American is Steve Rogers. That doesn't mean that John Walker, Bucky Barnes or Sam Wilson are lesser heroes. But I suppose Sam Wilson: Captain America sells better than a Falcon series.
