Marvel will just keep throwing bigger and badder villains ala DBZ, while heroes will have to be retired and replaced with younger versions of themselves or D-list faff like Ant-Man or whoever they dig up next.
Marvel's made a cinematic empire largely out of C and D listers. If they can keep doing what they do with the "faff," then by all means.

Or you know legacy characters...like what everyone is expecting of Cap sooner rather than later. Don't get me wrong you might have a point, but it is based on comics and comics doesn't care who dies. They might bring you back 6 weeks or 6 years later, and everyone knows that eventually every character will be back, but that sure has never stopped them from killing off characters and I don't see the movies being afraid of it either. Maybe Stark won't be going for a bit, but everyone that isn't Ironman, Thor, and Widow are fair game and more than likely someone is going to die and find their retirement with the reaper. Then they might be replaced by a D-lister or what have you. lol
Killing off a character and bringing them back strikes me as a decent opportunity to change actors. The question is, would they accept a replacement for RDJ or Chris Evans even in 6 years? Probably Evans, but Downey pretty much is Iron Man to the general viewing public. Would it look like anything but a reboot? I don't know, maybe the public won't care, considering they still go watch all the other superhero flicks.
With Iron Man and Cap, at least there's replacements in the wings, which are both comic canon friendly and have been set up. But I'm nt sure even that will be a long-term solution.
On the plus side, I doubt anyone would have even THOUGHT there would be a legacy issue when they started the MCU with guys like Cap and Iron Man.
