i think the easter eggs in marvel phase 2 are not really easter eggs. just because there is something that looks same doesn't mean it is the same.
i'm pretty sure kevin fiege or one of the phase 2 directors has stated that someone looses a hand in every phase 2 film as a nod to the empire strikes back.
All those Indiana Jones movies are just Han Solo`s dreams while he was stucked in carbonete
Don't forget the Millennium Falcon showing up in the Borg battle at the beginning of Star Trek: First Contact.
