I got the feeling we'll see Peggy only via flashback - considering Hayley brought up fighting/stunt scenes and Stanley Tucci said that he knew they would bring Peggy back for a flashback scene - but as I said, that's just my impression so I could be completely wrong.

I want it be something more than a flashback but I think you're probably right about it. Unless they told Stanley Tucci to keep some of it a secret so it's a surprise? I don't know.

I don't remember exactly what Stanley Tucci said, if he knew because he had talked to Hayley or from some other source. A present time reunion would be lovely, but perhaps Marvel would rather keep Peggy a memory for Steve if they are introducing a new love interest for him in the sequel, I don't know.

I can't remember either but I would have loved to see a reunion of them or even if it's just a dream maybe. For Steve to get some type of closure. I wonder if Peggy knew what happened to him though and if we could see something with that. Yeah, probably. It wouldn't work to make a triangle somehow.

Even if she wasn't informed before, when Steve was found, she would have seen him on the news after the attack of New York. So there's that. No idea if either Peggy or Steve wants to do anything about it, though. In the develed scene from The Avengers, Steve checks her file and stares at the phone but ultimately does nothing.

True. Do you think she thought he was dead until then? Maybe Steve thought it would ruin what they had because she aged and he didn't so he decided to just let it be. But it would have been sweet for them to hear each other's voice.

I think in the comics Steve met old Peggy at some point, so there is some canon the movie writers could use. Peggy likely thought him dead, so it must've been quite the shock to find out he was back, out of the blue. As for Steve, I believe he really feels disconnected from all, while everything he knew is either not there anymore or has completely moved on - Peggy is a fresh wound for him, but he might think of himself as just an old memory she might have no interest in revisiting. I agree with you that meeting Peggy would give him closure, though, especially considering that in the new film dealing with the past is a big theme, with Bucky's return.

It's weird but I love the idea of Peggy being the one who enables him to "let go" and move on from the life he left behind. I think she'd have that effect on him. If they have an old Pegs/Steve moment I may just cry my eyes out!

I'll be joining you with the bawling! ...If I don't have a heart attack first, lol.
I'd love for a scene like the one you have in mind - it would be a nice way to have Peggy once again be the person giving Steve the "right push" to the next stage of his life.
