The one Earth superhero who can detect a Skrull is ... Daredevil! He can't actually detect that they are Skrulls, but he can detect who is hiding some secret different from the secrets others might be hiding. As comics evidence, I cite Bendis' writing Daredevil's powers sort of this way when Matt Murdock was deducing who was harboring a demon in a support group, and I also cite Nick Fury's offer to Daredevil to join S.H.I.E.L.D. Now I don't think Fury was recruiting Matt Murdock because he knew he could detect Skrulls, but it would be a nice tie-in.

From a Marvel business standpoint, sales on Brubaker's Daredevil are good but not spectacular, similar to how sales were for Brubaker's Captain America before Civil War and the death of Captain America storyline. I therefore also predict that Daredevil will finally join the New Avengers. In addition, I believe that Spider-Man will eventually have to be replaced because of the events of OMD, therefore another Marvel heavyweight has to take Spider-Man's place.

I also wouldn't be surprised to see the Thing join the Avengers somewhere down the line considering that Bendis is including him apparently in the upcoming Doom storyline.
