Captain America dead?

Marvel's sweeping Civil War has taken the life of a very significant character.  Captain America has seemingly died when he was afflicted with a mortal wound while going to his trial.  Joe Q has this to say about comic book death:  "There was period in comics where characters would just die and then be resurrected. And the death had very little meaning and the resurrection had very little meaning," he said. "All I ask of my writers is if you're going to kill a character off, please let that death have some meaning in the overall scope of things."

So, is Cap dead-dead, or will he be returning?
