Um. Steve is already back in the page of Invaders vs. Avengers.
I don't read comics that much anymore. And in regards to that, I've only read Captain America #25, and only as part of the Civil War storyline.
Which really is just an expansion and a repeat of the Mutant Registration Act Storyline. Instead of just mutants its to any being with superhuman abilities of any sort.
And personally I've come to believe its an allegorical story about firearm registration. The parallels are there. The anti-firearm crowd believes that anybody who owns a firearm is a criminal that is simply out to kill your children and demonizes anybody who owns any kind of firearm. The same kind of attitude is behind the drive to outlaw supehuman beings.
