I mean I get that... if that is the purpose of the movie... I don't think it is suppose to set up Avengers, Captain America, Thor, or The next Hulk... It'll probably be something like...
-Government is trying to get him... Too bad... move onto next plot piece
-Shield is trying to get Tony's info... Too bad... Send in Black Widow... Fight sequence... they don't kill each other cuz she is hot... she says something about Tony's father... then she disappears for a hour...
- Somewhere in between those two, Whiplash is like (Your daddy killed my daddy, now I'm going to use your daddy's tech to kill you)
- Whiplash... I KILL YOUR RACE CAR... HERE COMES IRON MAN... oh ****... something is wrong... I barley beat you cuz my chest piece was ****ing up... dat how you got away
- Tony... oh ****... my chest piece is ****ing up... I'm dying...
- Tony... oh ****... my dad was a real hero... oh ****... gotta worry about dying... I'll save my response to my daddy issues until after the credits (Or and alt version of this is that Black Widow isn't with SHIELD yet and is actually with Hammer trying to get Starks tech... Tells Tony something horrible about his dad... plants to proof... Tony gets drunk and goes to hang out in a donut)
- While trying to figure out why he is dying Tony finds out his dad made robots and worked with some iteration of SHIELD back in the day...
- Rhodes is like... well... while Tony is busy... He might need to be replaced... enter Warmachine via Hammer... who gets the information he needs to activate the robo killers
- Awwww **** ya... Tony figures out his **** right in time to save the world from Robos...
- Some stuff that provides us closure happens
- Credits
- Enter Sam Jackson... Tony says... "I'll do it."
- The End
Well... Now that I write that all out... it does sounds a bit complicated...
