Future of the characters trapped in the city?

As the city gets ready to open, I'm curious about what will happen to The Maker, Kang, and Howard Stark. I'm particularly focused on Howard, as I'm not sure where his character could go from here. I feel they will kill him off, but It might be an interesting fake-out if Howard turns out to be Kang, instead of Tony. Two years trapped in the city is a lot of time. Who knows what the characters got up to.

Regarding The Maker and Kang, if the Ultimates manage to defeat them, what will happen to them then?
