If you throw in a few other titles you could probably make a list of all the Cap death related books. There aren't many, and I imagine it would be interesting to read some time. The other books that would be tossed in were you to do that now would be
-CW: The Confession -Punisher: War Journal 5
And arguably -CW: The Initative -New Avengers 28-31
It will be interesting having a comic titled "the death of Captain America: Captain America" Still, if they follow these 5 stages in this order, #2 and #4 will be interesing. Having Iron Man for "acceptance" seems somewhat disappointing though, but let's wait and see.
This is just s guess on my part which I am completely willing to say I am wrong about.
We see Cap viewing his situation from the other side of the mortal coil, or whatever. Caps would be a soul many of the supreme beings would want to vie for. i.e. Death, Mephisto,... like so. For instance you could see Mephisto offering Cap continued life in exchange for his soul.
Something along those lines would fill the 'bargaining' aspect of the storyline.
