Scriptdoctor guy gives his two cents...
***Spoiler Alert!!!***
Marvel plans to do Iron Man, Hulk, Captain America, Ant Man and Thor so that they can then do... The Avengers.
Boo-wow.
And the "S" will play more in the IM sequel scheduled for 2010, and yes, our "guy at the end" is here to stay -- blame that Ultimate Universe Millar dude for that (think of "Mr. Guy at the End" as an LMD or as a hologram disguise as presently used in "The Mighty Avengers" if it bugs you THAT much... Hell, they could have brought back Hasselhoff, you know.)
