Me being not that good of a comic nerd is hampering my informed guessing ability on this one. But rumored money is on Cap kicking the Bucket. Bucky is one of a few possible replacements. Wilson is a recent addition to that list as well. So if Chris Evan's Captain America goes, there are two contenders in place to take up his mantle. I don't know guys, whatever happens though those remaining will find the strength to carry on the good fight. Sooner or later the wounds will heal, and they all can focus on keeping their home safe from evil doers.
